Get the list of installed packages by user in R

Question

How we can get the list of installed packages by user in R along with its version?

I know about the command installed.packages() which will give information

Answer 1

Here's my solution.

tibble::tibble(
  Package = names(installed.packages()[,3]),
  Version = unname(installed.packages()[,3])
)

You can even filter some packages that you want to show.

pkg = tibble::tibble(
  Package = names(installed.packages()[,3]),
  Version = unname(installed.packages()[,3])
)

dplyr::filter(pkg, Package %in% c("tibble", "dplyr"))

Answer 2

ref

ip = as.data.frame(installed.packages()[,c(1,3:4)])
ip = ip[is.na(ip$Priority),1:2,drop=FALSE]
ip

Answer 3

str(allPackage <- installed.packages(.Library, priority = "high"))

allPackage [, c(1,3:5)]

You will get all the active package List

Answer 4

I just found another ways to see the list of the packages without writing any code:

• Open RStudio
• Navigate to Help --> R Help (from the menu above)
• You will see the help panel opened.
• Then follow, Reference --> Packages

There you are.

OR

• Open R console
• Navigate to Help --> Html help
• Then follow, Reference --> Packages

Answer 5

If I develop an app or model and want to record the package versions used, I call sessionInfo()
