Is there a file in your current working directory with this name?
You can determine your current working directory with getwd() and you
can set it with setwd().

This looks like your working directory is the R install dir.  Did you
put data files there?  Probably it is a better idea to place them
elsewhere and change your working directory.  There is a menu option
for it in the Windows R GUI, but you can also use setwd().

Putting those packages into the R directory seems strange.  You'll
need to give us more details in order to help.  But the first thing is
to get your file paths sorted.
