R session watcher does not work

I tried the following code with the session watcher open

library(tidyverse)
ggplot(data = mpg) + geom_point(mapping = aes(x = displ, y = hwy))

but it does not prompt anything.

I read about #179… but it seems not my problem

here is some more information might be useful.

> ls.str(getOption("vscodeR"))
attach : function ()  
dataview : function (x, title)

Thank you

The plot is printed because in an interactive session when you input an expression, the result will be printed, and ggplot2 graphics is only created when you print the result.

If you need the produce the plot in source, you may need the following:

plot <- ggplot(...)
print(plot)

for whom may interest, without having print(.), cmd+enter can have the same result
