image output format

[sniban]

Hello Ahmed A. Metwally,
I am trying to use MetaLonda remotely on university server. but while running I am not getting any image (empty image, 0 bite in size) as output with the following warning message:

Warning messages:
1: In grDevices::dev.off() : No jpeg support in this version of R
2: guides(<scale> = FALSE) is deprecated. Please use guides(<scale> = "none") instead.
3: In grDevices::dev.off() : No jpeg support in this version of R

then I tried to search the r version ( supported graphic formats using capabilities() it resulted in jpeg FALSE. So I wanted to know if its possible to get graphic output in different (png) format?
