Answer 1

When R installs a package, it evaluates all the ".R" source files and re-saves them into a binary format for faster loading. Therefore you typically cannot easily find the source file.

As has been suggested elsewhere, you can simply type the function name and see the source code, or download the source package and find the source there.

library(plyr)
ddply # prints the source for ddply

# See the content of the R directory for plyr,
# but it's only binary files:
dir(file.path(find.package("plyr"), "R"))
# [1] "plyr"     "plyr.rdb" "plyr.rdx"

# Get the source for the package:
download.packages("plyr", "~", type="source")

# ...then unpack and inspect the R directory...
