You should install the Rcpp package, as the error message is telling you. You could also use the dependencies=TRUE argument to install.packages(). Sarah On Mon, Mar 7, 2016 at 2:23 PM, jessy wrote: > Hi, > I am trying to install ggplot2 in R software but Im getting the following > error message

Re: [R] Problem installing ggplot2 in R 3.2.3

Apparently you do not have a required package installed that ggplot2 depends on. How you arrived at that condition is not clear because you have not told us the minimum information mentioned in the Posting Guide. Since the typical way to install ggplot2 is to use the install.packages( "ggplot2"

I think you would do better posting to a statistics list, like stats.stackexchange.com . Advice there might bring you back here to
