stat_ecdf() not currently working on provided examples on Ubuntu run RStudio server

[mariadelmarq]

I found a problem with stat_ecdf().

I expected the provided examples to work, however I get the error:

Warning: Computation failed in `stat_ecdf()`
Caused by error:
! attempt to apply non-function

Here is the code to reproduce the bug:

# copy your code to the clipboard and run:
library(ggplot2)
set.seed(1)
df <- data.frame(
  x = c(rnorm(100, 0, 3), rnorm(100, 0, 10)),
  g = gl(2, 100)
)
ggplot(df, aes(x)) +
  stat_ecdf(geom = "step")

If I put it into reprex::reprex(), then it works, but if I try to run it in my RStudio server console, or within an RMarkdown file, I get the error described above. Is it possible I'm missing some Ubuntu library?

Hi there,

It seems unlikely that you'd need additional system libraries, calculating eCDFs should work. Does the problem occur when you run this code in a new R session or knit a very minimal Rmarkdown file?

Thanks for your response, @teunbrand . Yesterday it didn't work in the console, in a minimal Rmarkdown file, or even by clicking on "Run examples" in the help at the bottom right. Today it works! I have no idea what happened, so sorry to waste your time.
