error when installing rcpp in rstudio on ubuntu 14.04:

installing source package ‘rcpp’ ...
package ‘rcpp’ unpacked , md5 sums checked warning in file.copy(f, instdir, true) : problem copying ./namespace /home/briangriner/r/x86_64-pc-linux-gnu-library/3.2/rcpp/namespace: permission denied warning in file(file, ifelse(append, "a", "w")) :
cannot open file '/home/briangriner/r/x86_64-pc-linux-gnu-library/3.2/rcpp/description':
permission denied error in file(file, ifelse(append, "a", "w")) : cannot open connection error: installing package description failed package ‘rcpp’
removing ‘/home/briangriner/r/x86_64-pc-linux-gnu-library/3.2/rcpp’

i think error is

problem copying ./namespace /home/briangriner/r/x86_64-pc-linux-gnu-library/3.2/rcpp/namespace: permission denied

check permissions on rcpp directory, or remove , reinstall rcpp. you're on ubuntu can install (probably little older) binary package r-cran-rcpp.
