@samirasadri

R6

I am not a Windows user but it looks like you should install {R6} and try again

install.packages("R6")
install.packages("ggplot2")

I think this is the actual error you have to solve - it seems that your local windows server is having issues with SSL connection to cran.rstudio.com. This can be triggered by general windows setup issues, firewalls, transparent proxies etc...

Do package installations work with other R versions on the same server ?

[samirasadri]
