- This video shows you how you can simply create country maps in R and then colour code countries according to some data, in this case % of the population having received a covid vaccine. I'll show you how you can alter the map properties and even put your own logo on the map.
Data and code used in the video can be found here drive.google.com/drive/folder...

Simple, clear, to the point and very easy to follow at the same time. Thank you for this nice work.
Thank you
Best explanation of mapping in R I have found till now and I have been researching a lot!
Thank you!
It's a clear and straigthforward explanation. Thanks.
Your tutorial helped me a lot in plotting my data. Thanks.
This was so helpful. Saved me alot of time cheers.
Really good video, keep it up mate!
Thanks for this simple and clear video. It was super helpul
Thank you. So concise and helpful.
Cool tutorial, thanks! I'm just getting into R and I found this to be very helpful.
Edit: Give my regards to Bill too.
Thank you for this video! How would you go about keeping the records of NA values to still have the country showing on the map but blank on the inside so it does not influence the color scale of the legend?
I love your tutorial, it was quite helpful when I was trying to do a map.
Is it possible to add countries to the map with a value of 0?, maybe not in the gradient, but afterward just add a country?
That would be very helpful to me.
Very instructive video. Thanks.
Thank you for a wonderful presentation
Thanks for the tutorial and the codes.
Thanks!, Really helpful better than my textbook!!
Super easy to follow, thanks!
Thanks. Although instead of a left join and then filtering you would probably get the same result with a right join
Thank you! the video was really helping to get me started4
Super helpful video! Would it be possible to add the NA value to a separate legend to say that NA = grey on your map? :)
fabulous! what do you do if you do not have and equivalent value in your dataset for region (or any other)? instead, one might have "area" or "code"
Some of the countries look a bit distorted such as Spain and Iceland. You might play with the projection type by changing the "crs" (coordinate reference system).
Found the GIS guy! 😄
Extremely helpful video
Nice video and I was looking for this type of material to plot my data. I will try and soon and hopeful that I can replicate the same.
Great video. Thank you.
Hi! Very informative tutorial - if we want to rather have a different colour for each country (not based on any number data), R will automatically assign some colours - how do we change them?
It's useful. Thank you so much.
Thanks for this video! I had created my first map of the world. For some reason I have a missing gap of South Africa missing while the rest of the countries are present. Is there something wrong with my dataset?
Hello, thanks for the video . I wonder where you found your map.shp because i actually need to find one of the France.
Thank you soooo much!!! Blessings
Great video! Any Idea how I can add country names to the map? Thanks
Was it possible instead of using a left join and then filter, to just have done an inner join?
Nice demo of ggplot plotting maps.
There is a short-cut for eliminating NAs - namely: drop_na(Perc_vaccinated).
Wow. Thank you. I love you
hello! i couldn't make some of the countries lighter and other darker depending on their value. is there something i can do to fix that?
hi, how to solve the problem of incompatible types when i do left_join function? thanks
can we modify the geometry part of a shapefile??
thanks~!
How did you add a percentage column to the world map table?
For filtering the map down to EU countries only when i use the code - mapdata1% filter(!is.na(mapdata$`All antibiotics`))
View(mapdata1) ``` i get an error message: Error in UseMethod("filter") :
no applicable method for 'filter' applied to an object of class "c('gg', 'ggplot')" -- any help with this?? thank you
How can I get the map data for the entire world? I am trying to View but it displays an error
Amazing video, super helpful! Do you have a video yet on how to animate it? I have data from 2005 to 2020 and would love to animate this map?
Not yet, gganimate package will do it for you, I will get around to making an animation video soon!
Hi, this tutorial is really good and easy to follow, I have created the same map, But I'm having difficulty adding scale_bar or annotation_scale, Could you please show this to viewer how they can add these scales.
Hello, Im just trying to put data lebel on the region. But i cant do it. Tried a lot. Can you tell me how to do it?
Helpful
Thank you so much!
Amazing video, super helpful! Question, on line 17 of the code where you go to filter the mapdata, what does %>% do ? My R does not recognize it as a function and won't let me filter it with that
It's from tidyverse and is called a pipe style.tidyverse.org/pipes.html it just executes operations taking an input and giving an output. Install tidyverse and it should work!
Any reason "united States" is missing when creating mapdata?
Good video it is.
It looks like map_data is no longer supported by ggplot2. Do you know what it was replaced with?
What can you do when their is not a mutual variable between the map data and my own dataset ('region' was the example given here). My countries are also coded indifferently to map data, will these cause some issues? Any help would be very much appreciated for my dissertation! (I'm very new to R)
did you manage to get this sorted?
OHHHHH I get it！I made a mistake by excluding gorup=group in aes and got a messed up map, now corrected it
its not showing Democratic Republic of Congo and Congo Kinshasa, any reason, maybe input names are different. United States will only load when wriiten as USA. thanks for a great workshop
is it possible to label the countries on the map ?
thank you!!
So I have a dataset with volcano names as well as their own longitudes and latitudes. Is there any way I can plot that data into a map that shows their locations as points using this method?
You can use something like this to do that th-cam.com/video/SdvGzbOZ-Qs/w-d-xo.html
Hi! Great video! But I always get the notification "Error in left_join(mapdata, fieldworkplaces, by = "region") : could not find function "left_join"". Any ideas on how to solve this? Thanks!
Install the dplyr package
What is the best way to get the map data 1? I've watched every video on TH-cam from beginning to end, but I'm still unable to locate the vaccination percentage map. Is there a solution?

Thank you for this video!
them_void in base ggplot2 removes all the axis stuff for you so you don't have to write it out
Is there any way to add to this map another variable that is illustrated for example by bubbles/dots, in addition to the existing one? Thanks!
Looking to get the provinces of Canada for a map but the world data does not provide this, do you know of any datasets that do?

How can I use my own shape file
Thank you for uploading a wonderful tutorial.
I have a query that how we can plot two variables data on single map.
Like :
ggplot() +
geom_sf(data=shape, color='grey20', size=0.1, fill=NA) +
geom_sf(data = subset(clus_dzc1, type=='high'),aes(fill=CL2),size=0.1,color='black') +
scale_fill_discrete_sequential(palette='Burg',name="High-risk",rev=FALSE,
guide = guide_legend(ncol=2)) +
theme_void()
ggplot() +
geom_sf(data=shape, color='grey20', size=0.1, fill=NA) +
geom_sf(data = subset(clus_dzc1, type=='low'),aes(fill=CL2), size=0.1, color='black') +
scale_fill_discrete_sequential(palette='Blues',name="Low-risk",rev=FALSE,
guide = guide_legend(ncol=2)) +
theme_void()
. There are two plots code. Can you please guide me, how i can convert into one gg plot. Can you please write the code for me.
I shall be very thankful to you.

Can anybody help me with my data? I am struggling with errors. It is for my thesis.
I have put in all the code and nothing is coming out at all
Thanks.
Does it work for r4.1
Can we select the other regions examples china, taiwan, Frances?
yes, all countries can be done, I limited them to the ones I had vaccination data for.
@@DrPC_statistics_guides thanks Dr. I Just successful do it awesome.
Great video! I followed it; however, the USA is not showing up on my map.
Try,
world_map$region[world_map$region == "USA"] = "United States"
that should fix it!
Hey, how do you add labels on the countries?
Did you find a way to add the country names ?
I'm completely new to it but the view part will not run, does not recognize object
I have just ran all the code and it all works fine, I imagine that you have a slight mismatch between what you have called the object and what you are asking to View()
Here are all the cases were there is an object defined + a view in the script that's linked below the video

@@DrPC_statistics_guides sorry I really didn't expect a reply 😅
@@DrPC_statistics_guides, It's a great video. I am trying to plot it, but from where I may get the mapdata? I am finding "Error: object 'map1' not found".
how can i get the map1 data ?
