When I run install.packages("xlsx") I get this:

Installing package into ‘C:/Users/Zahra/Documents/R/win-library/3.1’ (as ‘lib’ is unspecified) Warning: unable to access index for repository https://rweb.quant.ku.edu/cran/bin/windows/contrib/3.1 Warning: unable to access index for repository http://www.rforge.net/bin/windows/contrib/3.1 Warning message: package ‘xlsx’ is not available (as a binary package for R version 3.1.3)

I already tried setRepositories and a couple of more things but no luck! I appreciate any comments

rinstall.packages
Can you install other packages? Are you sure your internet connection isn't being blocked? Have you tried other CRAN mirrors (chooseCRANmirror())? – MrFlick
The second url is broken; however, the first url indeed includes xlsx_0.5.7 (the most recent version listed on CRAN), and I was able to download it directly from there. – MichaelChirico
I have not been able to install any other package, xlsReadWrite,perl,... – nasim
And yes my internet connection works – nasim
You have install.packages("xslx") - do you mean xlsx? – Sam Firke

I found my own answer! I figured the problem was that for installing all those packages, the required package was "rjava" that couldn't be loaded. The reason was the fact I am using a 64-bit OS and R version but do not have Java installed with the same architecture.I downloaded Java 64-bit(Windows Offline (64-bit)) from this page: https://www.java.com/en/download/manual.jsp After that just reloaded the xlsx package and it worked
