Is there a function in R that return Package Depends, Imports and LinkingTo?

In CRAN, each package has Package Depends, Imports and LinkingTo http://cran.r-project.org/web/packages/Rcpp/index.html. Is there a build-in function or a function from an R package that can return the same information? Thanks.

Sure. Both available.packages() and installed.packages() have it:

R> AP <- available.packages()
R> dim(AP)
[1] 6793   17
R> AP[1:5, c("Depends", "Imports", "LinkingTo")]

The package DESCRIPTION file has this info. The function in the utils package packageDescription will parse and read this. See ?packageDescription
