You failed to install imager. Try to install imager just after launching R.

remove.packages("imager")
install.packages("imager")
library(imager)

It looks like you're on OS X and need to install XQuartz. Sorry for the obscure error message, the next version should have something more explicit.

Hi @ShotaOchi I try the code, but I get this same error that happens before. Hi @dahtah I download XQuartz X11 for Mac and follow the instruction to install it.

Finally, It works! Thank you very much!
