I have been trying to install the proper programs to get a code to work (it will create a dose-response curve). At first I was trying to install package drc, but it would come up with an error saying how that package was written with R 3.3. The version of R I was using was older than that, so I updated R to the newest version: R 3.6.1. I tried to install drc again. It still isn't working. This time, it's coming up with the following error:
Error in readRDS(pfile) : cannot read workspace version 3 written by R 3.6.1; need R 3.5.0 or newer
It comes up as the last error when I attempt to install.packages('drc'), but it also shows up in multiple rows as it attempts to run the command.
I have the most recent version of RStudio.
Any help would be appreciated.
