[R] ggarrange & legend

[Ebert,Timothy Aaron]

Would something like this help?
library(ggplot2)

# Create a plot
p <- ggplot(mtcars, aes(x = wt, y = mpg)) +
  geom_point() +
  labs(title = "Scatter Plot", x = "Weight", y = "Miles Per Gallon")

# Add text at a specific location
p + annotate("text", x = min(mtcars$wt) + 23, y = max(mtcars$mpg) - 10, label = "Custom Text")

Dear John Kane

Dear R community



Here my working example

1.      Example that is working with legend="top". However, as mentioned, the legend is in the middle of the top axis.

mylist<-list(p1, p2)

dev.new(width=28, height=18)

fig1<- ggarrange(plotlist=mylist, common.legend = TRUE, legend="top", labels = c("(A)", "(B)"), font.label = list(size = 18, color = "black"), ncol=2)

fig1



2.      My question is how I can position the legend on the topright of the top axis. However, "topright" is not a common label for legend in ggarrange (but in other plot functions), so legend ="topright" is not working.

mylist<-list(p1, p2)

dev.new(width=28, height=18)

fig1<- ggarrange(plotlist=mylist, common.legend = TRUE, legend="topright", labels = c("(A)", "(B)"), font.label = list(size = 18, color = "black"), ncol=2)

fig1



Kind regards

Sibylle

Could you supply us with a MWE (minimal working example)of what you have so far?

Thanks.

It is possible to adjust the legend in combined ggplots using ggarrange with be positions top, bottom, left and right.
My question: Is there a function to change the position of the legend to topright or bottomleft? Right and top etc are in the middle of the axis.

Kind regards
Sibylle
