Error in install.packages : type ==“both” cannot b

Question

Actually I am trying to install packages offline. I have R studio. what I do is based on previously asked question as follows:

install.packages(C:/Users/Desktop/class_7.3-12.zip", repos = NULL)

I get the error I mentioned in the title. is someone out there to give me an advice ?

Thanks

You can install packages from source or binaries. In the "Package Archives" section of the documentation you may read:

Package Source class_7.3-12.tar.gz

Windows Binary class_7.3-12.zip

(32- & 64-bit) Mac OS X 10.9 (Mavericks) class_7.3-12.tgz

When installing from binary (as it seems to be your case):

install.packages("class_7.3-12.zip", repos = NULL, type="binary")

Otherwise, when installing from source:

install.packages("class_7.3-12.tar.gz", repos = NULL, type="source")
