It keeps saying that package is not valid despite being installed

[Renren]

Hi,

I have run the install.packages function to install the 'pROC' package. It says: "the downloaded binary packages are in" and then specifies a path location. However, when I then run the library(pROC) command, it keeps giving the following error:

Error in library(pROC). pROC is not a valid installed package

Any help regarding to solve this issue would be much appreciated. Thanks in advance

Very likely the package is not being installed successfully. Please post the complete console output you get when you try to install it

install.packages("pROC")

The package is not installing successfully because you don't seem to have write permissions on the package library folder (which by the way is not on a standard location). Are you executing RStudio as "Administrator"? If not, give it a try, otherwise, modify the folder permissions to allow your user to write on it.
