Sometimes, I got some R code without the information of loaded packages. For example,
x <- thisisafunction(data)
and I have no idea which package thisisafunction
is coming from. I want to find all packages which contain thisisafunction
function in CRAN. This package may or may not have been installed in the current machine. Is it possible to do this? I tried googling the package name, sometimes it works but sometimes it doesn't.
