How to create the plots arranged in a list that were generated using ggplot2 in R?
If we have two plots generated by using ggplot2 and arranged in a list then we can create them using ggarrange function. For example, if we have two objects p1 and p2 that are stored in the list called named as LIST then those plots can be created in the plot window by using the command ggarrange(plotlist=LIST,widths=c(2,1),labels=c("Scatter","Hist"))
Example
Consider the below data frame −
set.seed(21) x<−rnorm(20) y<−rnorm(20) df<−data.frame(x,y) df
Output
x y 1 0.793013171 0.39299759 2 0.522251264 0.03675713 3 1.746222241 -1.03208366 4 −1.271336123 −1.26486147 5 2.197389533 −0.22696529 6 0.433130777 0.74558930 7 −1.570199630 0.33281918 8 −0.934905667 −1.12404046 9 0.063493345 −0.70613078 10 −0.002393336 −0.72754386 11 −2.276781240 −1.83431439 12 0.757412225 −0.40768794 13 −0.548405554 0.02686119 14 0.172549478 0.91162864 15 0.562853068 1.63434648 16 1.511817959 0.06068561 17 0.659025169 1.84757253 18 1.122028075 0.08012495 19 −0.784641369 1.41855588 20 −0.425692289 1.45861594
Loading the ggplot2 package and creating the plots −
Example
library(ggplot2)
Scatterplot<−ggplot(df,aes(x,y))+geom_point()
Hist_of_x<−ggplot(df,aes(x))+geom_histogram(bins=30)
List<−list(Scatterplot,Hist_of_x)
ggarrange(plotlist=List,widths=c(2,1),labels=c("Scatter","Hist"))Output
