Trouble Installing Quantmod

Hi everyone,

I recently migrated to Linux from Windows and have R installed on my
computer with no problems with one exception: I can't install quantmod or
TTR.

When I use the command:

install.packages("TTR")

I get the below message:

*Installing package into ?/home/peter/R/x86_64-pc-linux-gnu-library/3.0?
(as ?lib? is unspecified)

Warning in install.packages :
  installation of package ?TTR? had non-zero exit status

The downloaded source packages are in
        ?/tmp/RtmpjtCmgS/downloaded_packages?*



The problem is that this doesn't show up in the packages listing in R
Studio and when I attempt to load it with the library() command I get the
below response:

*Error in library(TTR) : ?TTR? is not a valid installed package*

This continues even though I have used the lib.loc command to try to
install these directly to the directory where the other packages are.
Additionally, I have also manually moved them to said directory but
with no luck.

Any help would be greatly appreciated!

Thank you,
