If you have the code in a parseable form then CodeDepends will try to do
this:
> library(CodeDepends)
> code
[1] "w = rnorm(10); t = read.csv('mycsv.csv'); lm(y~x, data = t)"
> scr = readScript("dummy", type = "R", txt = code)
> inp = getInputs(scr)
> length(inp)
[1] 3
> inp[[2]]@files
[1] "mycsv.csv"
The package is not currently on CRAN, but is available from the author
Duncan Temple Lang's github account:
https://github.com/duncantl/CodeDepends
There is also work going on for a more comprehensive solution:
