I'm trying to install the deSolve package in R by using install.packages("deSolve")
and it returned the error message: package ‘deSolve’ is not available (for R version 3.6.2).
Also tried installing through other packages that contain deSolve as dependency, same error occurred:
Warning in install.packages : dependency ‘deSolve’ is not available
I'm wondering is there anything that I'm missing?
