[R] Exporting Charts or Graphs

[Jess Balint]

Hello all, I am fairly new to R and hope not to be a bother. I have used the R-GUI a small amount under Microsoft Windows0S. I recall the ability to export created charts and graphs to JPEG or other various image formats. How can I do this in the UNIX CLI version? Thank you.

Also, I have receiveder the following error after installing a package via CRAN. How would I fix this? Thank you.

Jess
