How to create Multi-Panel plots in R with facet_wrap() and facet_grid()

In this video, I will show you how to use facet_wrap or facet_grid to create multi-panel plots in R and ggplot.
Faceting plots can be very helpful to compare your data over different categories.
It can also help you to get a quick overview of your data across multiple variables if you use a special pivot longer trick.

Thanks for watching, liking and commenting :)
I wanted to include as much as possible without being to long or boring. Next video will be about pie charts.

scale_x_reordered function seems useful

[@GaboMoya]

I have a question. How do u change the order of the desplay. The factet grid follows alphabetical order. But i need and special order. For example the order in min 7:09 its Africa, Americas, Asia, Europe. But what if u want Europe first?

[@TheDataDigest]

You have to use the factor() function and provide a new order of the levels. For example like this:
gapminder$continent2

[@TheDataDigest]

Just for transparency: I orginally used "labels" but it has to be "levels" otherwise the Africa data just got re-labeld with Europe instead of ordering the levels new.

I have a dedicated video about reordering factors: th-cam.com/video/ChhJUN1JDLI/w-d-xo.html

14:19 i still fail doing that chart 😅

[@TheDataDigest]

What error message are you getting? Did you load the tidytext package to have the reorder_within() function available?

[@Zoyfad]

thanks for the video:)
btw dplyr::slice_ functions are nice
diamonds %>%
slice_sample(n = 5000)

[@TheDataDigest]

Thanks for the feedback. Really great to have someone that posts some extra useful functions. I knew the slice() function and remember now using it in the past after arrange to only select the top 3 of something. But wasn't aware that there is slice_sample(). So thanks again :)
