问题
I am trying to install package forecast in R using below command
install.packages("forecast")
, but getting message that
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.3/forecast_8.2.zip' Content type 'application/zip' length 2076974 bytes (2.0 MB) downloaded 2.0 MB
package ‘forecast’ successfully unpacked and MD5 sums checked Warning in install.packages : cannot remove prior installation of package ‘forecast’
I manually removed package from local folder as remove.package was also not working, can anyone help me here and let me know what is the issue
