Fixing the position of Text box in plot window in ggplot-CodePudding

I have below ggplot :-

library(dplyr)
library(ggplot2)
library(ggtext)
library(ggdist)
set.seed(1)

DF = rbind(data.frame('Label' = 'A', val = rnorm(200, 5)), data.frame('Label' = 'B', val = rnorm(500, 10)))

DF %>%
ggplot(aes(x=Label, y=val, fill=Label, alpha = 1))  
stat_dots()  
geom_textbox(x = -Inf, y = -Inf, label = 'My text', width = unit(0.4, "npc"), height = unit(0.04, "npc"), box.margin = unit(c(1, 1, 1, 1), "pt"))

I wanted to fix the position of the textbox at the bottom-left region of the window irrespective of the plot window size.

However above code is failing to achieve the same. I am getting below error with my plot window

Error in grid.Call.graphics(C_upviewport, as.integer(n)) : 
  cannot pop the top-level viewport ('grid' and 'graphics' output mixed?)

I am using R with MacOS.

Any pointer how to fix the position of this textbox at the bottom-left position will be very helpful.

CodePudding user response：

Be sure that aes and data in geom_textbox override ggplot().

library(ggplot2)
library(ggtext)
library(ggdist)

set.seed(123)
DF <- rbind(data.frame('Label' = 'A', val = rnorm(200, 5)), 
            data.frame('Label' = 'B', val = rnorm(500, 10)))

ggplot(DF, aes(Label, val))  
  stat_dots(aes(fill = Label))  
  geom_textbox(aes(-Inf, -Inf, hjust = 0, vjust = 0, label = "My text"), 
    data.frame())
