Warning in install.packages : cannot open: HTTP status was '404 Not Found'
install.packages, package, r
Solution
as I can see there is no "memoise_0.1.zip" at http://cran.rstudio.com/bin/windows/contrib/3.0/ . However, there is the "memoise_0.2.1.zip" file.
What version of RStudio IDE are you using? Do you have memoise already installed? Maybe you should try to update the memoise package.
Problem
I have attempted to download R package `memoise`: ``` install.packages("memoise") ``` However, I have recevied the following error message: trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.0/memoise_0.1.zip' Warning in install.packages : cannot open: HTTP status was '404 Not Found' Error in download.file(url, destfile, method, mode = "wb", ...) : cannot open URL 'http://cran.rstudio.com/bin/windows/contrib/3.0/memoise_0.1.zip' Warning in install.packages : download of package ‘memoise’ failed` I am connected to the internet and the WWW. In addition, I am connected to a work network. I am using the RStudio IDE. Does anyone have any advice for how I troubleshoot this problem?
