As the subject says I am about to migrate all my work to a new machine and I would like to know if there are any best practices for doing so. Like can I get a list of all packages on my machine with its versions and use that to install it on my new machine.
Thank you.
You can make a table with installed.packages():
ip <- installed.packages()
head(ip)
# Package LibPath Version Priority
# acepack "acepack" "C:/Users/nwerth/Documents/R/win-library/3.6" "1.4.1" NA
# acs "acs" "C:/Users/nwerth/Documents/R/win-library/3.6" "2.1.4" NA
# askpass "askpass" "C:/Users/nwerth/Documents/R/win-library/3.6" "1.1" NA
# assertthat "assertthat" "C:/Users/nwerth/Documents/R/win-library/3.6" "0.2.1" NA

Just keep the names from the "Package" column to use when installing again. If you want to freeze your package versions, then see if the renv package meets your needs. I haven't used it, but it sounds like it might help.
Thank you. I get this will get me the list of all packages I want to install on my new machine. But do I have a way to install separate them by CRAN and non CRAN.
