I was able to install the curl library with no problems. However, when I
tried to install ggplot (install.packages("ggplot2")), I got the same
message as earlier, that R can't load internet.so.

Thanks for your help!

I needed to update R so I could install ggplot. I am running Ubuntu

12.04.

I cannot upgrade Ubuntu because I am using a work computer.

I tried upgrading the normal way:

sudo apt-get update
sudo apt-get install r-base r-base-dev

But this only installed an earlier version. Finally I tried installing

from

source (./configure, Make install). This worked. However, when I try to
install packages, I get this error:

Error in download.file(url, destfile = f, quiet = TRUE) :
 internet routines cannot be loaded
In addition: Warning message:
In download.file(url, destfile = f, quiet = TRUE) :
 unable to load shared object '/usr/local/lib/R/modules//internet.so':

ls /usr/local/lib/R/modules/
R_X11.so  R_de.so  internet.so  lapack.so

Thanks!
