ggplot2 - Why is GGally::ggpairs significantly slower in RStudio vs. base R? -


per title, know why rendering ggpairs plot ggally package takes longer in rstudio vs. base r (or terminal)?

example:

start.time <- sys.time() ggpairs(mtcars) end.time <- sys.time() time.taken <- end.time - start.time time.taken

running in rstudio on machine takes on order of 5 times longer base r. have experienced same slow down regardless of os (windows vs. mac).

are there workarounds?

other packages?

specifically, how render like: ggally::ggpairs(iris, color = "species") without leaving rstudio?

i had similar issues, , spent time trying figure out why. found 4 significant issues (not exhaustive list). if situation mine, 1 , 2 main concerns.

  1. the ide. rstudio performs ggpairs slower r.
  2. your computing environment. don't have resources test extensively, we're talking gpu, since graphics processing issue.
  3. number of variables. more variables = exponential growth in time.
  4. sequential operations. if working on low-power machine, slow execution many requests.
