Error Information:
install.packages("ggplot2")
Warning in install.packages :
unable to access index for repository https://cran.curtin.edu.au/src/contrib:
cannot open URL '...../PACKAGES'
Steps taken so far -
Trying to install any package in RStudio or R Terminal using install.packages("ggplot2")
I get the about error messages.
I have tried disabling "Use secure download method for HTTP" in the Tools -> Global Options -> Packages
I have tried changing different CRAN Repositories.
I have tried install.packages('ggplot2', dependencies=TRUE, repos='....')
It's as if R is using a proxy?
I am not behind a firewall, but working from home.
If I put the URLS which R Studio is failing to open into the browser (https://cran.curtin.edu.au/src/contrib/PACKAGES) I get a response, so Its R Studio and R not connecting to the internet.
Old posts talk about disabling useProxy setting, but in the current version of R Studio this option doesn't seem to exist.
