You're doing a wonderful job, Dr. Burkey. Just so you know, I am an R user now and have been for the past 5 close to 6 years thanks to your videos. I have become an R trainer and I am a big R "evangelist" now.
Great videos so far! In response to the question you raised about how to select all the fields when joining layers, simply leaving that box unchecked will automatically include all columns in the resulting join. Looking forward to more!
Hi Dr. Mark, about the selection of the fields on the add Vector Join. What I found easier for me is to select the first field with one click as usual, but instead of selecting the next ones with a click I found that if you click the down arrow on your keyboard and then select the space bar the checkbox gets selected in a less tedious way. Thank you for your videos
First of all, Thank you very much for these great videos. One observation: I think you don't need to create field and then calculate FIPS later, like 2 steps. The field editor can both create and calculate at the same time. (At least it works in QGIS3).
This is 10 times more complicated than what I have the time and energy to get into for my project. I just need a very simple map. Only 1 time. There are no guide for it anywhere online. And this guide is good, but it's for complicated big projects only. Basically I would need to spend 5 times as long on setting this up and finding the functions than making the single map.
Well, sorry about that! I am not really a map guy, but more about setting things up for doing spatial statistics. If there is something very simple I can help you with, let me know... maybe I can help.
@@BurkeyAcademy It's fine. It's just a video that appeared at a Google search. All the other videos didn't even give me any kind of guide. This is the only video or instruction I have been able to find on this. It would be fun to do stats on this stuff for sure. But then I would want to get paid for it or something. Or maybe do some project I was really interested in. As a hobby I want to stick to smaller stuff that is fun to show.
Hi professor, when I have created a joint dataset and imput it into R, the R doesn't treat data from the csv file as numbers but characters. How do I suppose to solve the problem? (when I use the summary command, R calculates the mean, max, min etc. of those data that exist in the original shp file, but only sums the rest up by listing how many observation each number has rather than calculating them.) Thanks!
This might be becasue you have commas or $ or other signs in the data, or you are using a comma instead of a period as a decimal point? You can try to fix the variables that are being treated as character variables with a command like data1$newvar
One question, how does QGIS know (from the shape file) how the regions are spatially located? How is the map made? Since in the shape spreadsheet there isn't any variable defining their geographical location? But only GEO_ID, STATE, COUNTY, NAME, LSAD and CENSUSAREA.
The "SHP" file is actually a collection of files- only one of which is "the data". Additionally, there are files telling the GIS program the boundaries (for polygons) or the points (for point files), and information about what these coordinates mean (the location, and scale). I am not an expert, but most maps we normally think of are defined by polygons, which in turn are defined by the location of their vertices (corners). Let me know if you'd like to know more, and maybe I can research it and make a video. ☺
@@BurkeyAcademy no need for a in-deep video, but thanks very much for the availability. So, if I am getting it right, the collection of files that accompany the .shp file (and gives such info) are the .dbf , .prj , .shx and .xml ? So, whenever I use the .shp file, I need them to be in the same working directory, otherwise .shp will not work, correct?
I am working on Windows 10...And yes, I get the new concatenated column FIPS2, but when I want to open the csv, I select the file, I can see it and select no geometry and when I click OK the software crashes.
I don't know man- if anyone has any suggestions, please let us know! I posted the final shapefile here so you can work with it: sites.google.com/a/burkeyacademy.com/spatial/home/files/2.1%20NCVA%20CO%20Variables%20Shapefile.zip?attredirects=0&d=1
What version of qgis are you using? try uninstalling the most recent and go to a more stable build. If you are using creator's edition (windows patch) there may be some issues they havent fixed yet
Ignoring the "Choose which field..." option defaults to bringing in ALL data columns. At least that is the case in version 3. Thank you for the lectures, all very useful.
Just to be clear- you are clicking the "," button in QGIS, and QGIS crashes? I'm not sure what could be going on. What platform are you on (Windows, Mac?)
Thanks again!!...The strange thing is that I do not get any other "error message" until the sofware crashes..I will try in another computer...Keep them coming!!!
Please let me know if you figure anything out or if the other computer works. Maybe I somehow skipped something that is screwing people up. If anyone can help, let's chat over on my Reddit page and help each other out. www.reddit.com/r/BurkeyAcademy/

Excellent! Great to hear. Hopeully in August we'll get to some spatial econometrics in R.
Can't wait for it, sir.
I've been trying to find a spatial analysis tutorial for some tome now. Thank you for doing this. They're great.
Great videos so far! In response to the question you raised about how to select all the fields when joining layers, simply leaving that box unchecked will automatically include all columns in the resulting join. Looking forward to more!
Thanks a lot Dr Burkey!
Wonderful lecture! It seems the best function of QGIS is JOINS function,because it can conbine map data with txt data into a Spatial Data Set.
This is Great! Can't wait for the next one.
Thanks so much for the feedback!
Thank you very much!

Hello Sir, Thank you very much ! But what's the solution to create spatial panel dataset ?
