I used R 3.5.3 with Rstudio 1.1.463,and install.package() from CRAN before.
Today I tried checkpoint("2019-12-11",R.version = "3.5.3", verbose = TRUE) but lots of packages not installed well as below:
> library(checkpoint)
checkpoint: Part of the Reproducible R Toolkit from Microsoft
https://mran.microsoft.com/documents/rro/reproducibility/
> checkpoint("2019-12-11",R.version = "3.5.3", verbose = TRUE)

I think MRAN include all CRAN packages,but not.
For example,I search https://mran.revolutionanalytics.com/packages ,there's no package named tree,but I can find this package in https://cran.r-project.org/web/packages/tree/
I raise questions:
1.Does MRAN include all CRAN packages start at year 2019?
2.How to install not available in repository and won't be installed packages through checkpoint?
