I am making a figure for the publication. All my plots were plotted using ggplot in R. Now I want to arrange them into one figure. I am using gridExtra
package like this but I want to directly arrange along with labels such as A),B) etc..
library(ggplot2)
library(gridExtra)
c <- ggplot(mtcars, aes(factor(cyl),mpg))
P1 <- c + geom_boxplot()
P2 <- c + geom_point()
grid.arrange(P1,P2)
Resultant plot
But I want to label the plots as A. B. like this
Is there a way to do this??
