无法在R 3.2.1中安装xlsx软件包

Question

I am using Rstudio 3.2.1. And am unable to install the xlsx package. Following is what I did and received:

install.packages("xlsx")

Warning in install.packages :

  unable to access index for repository /src/contrib

Installing package into ‘C:/Users/shivanshu/Documents/R/win-library/3.2’

(as ‘lib’ is unspecified)

Warning in install.packages :

  unable to access index for repository /src/contrib

Warning in install.packages :

  package ‘xlsx’ is not available (for R version 3.2.1)

Warning in install.packages :

  unable to access index for repository /bin/windows/contrib/3.2

How can I fix this problem?

Answer 1

It may be a problem with your mirror. Try selecting global mirror from CRAN. If this doesn't work, then you may have a problem with a firewall or proxy.
