downgrading a package in R - r

Question

I recently installed the forecast package, using install.packages().
The latest version (6.1) has been successfully installed but I want to install the forecast package version 5.9. So I used :
install.packages('http://cran.rstudio.com/src/contrib/Archive/forecast/forecast_5.9.tar.gz', repos=NULL, type='source')
But when using library I get an error:
install.packages('http://cran.rstudio.com/src/contrib/Archive/forecast/forecast_5.9.tar.gz', repos=NULL, type='source')
Installing package into ‘C:/Users/.../Documents/R/win-library/3.2’

Here is the way to install forecast version 5.9(Its not a problem if you have forecast 6.1 already installed,it would install 5.9 separately meaning that you would see two forecast packages in the installed packages ).
Go to the link https://cran.r-project.org/src/contrib/Archive/forecast/
Download forecast 5.9(just click on it,it would start downloading the file.
Now open the R studio,click on install packages and change install from to : Package archive File(and just browse it to the location of zip file).And your package would be installed.
While using the forecast package in my case it didnt work(the function that uses forecast package) when both the forecast package where loaded.So i use forecast 5.9 making sure that 6.1 isnt loaded.
Hope that helps
