I have R 3.4 and would like to install superheat. I tried
install.packages("C://Users//me//Downloads//superheat-0.1.0.tar.gz")
and got a warning in install.packages:
package ‘C://Users//me//Downloads//superheat-0.1.0.tar.gz’ is not available (for R version 3.4.0)n error
Do I need an earlier version of R?
