How to generate dependency file that can be used by gnu make?
I don't think this function is same as gcc's option -MM. Because gcc checks pre-compile command #include, in which the filename can be fetched definitely. But in your scenario, the filename may be from some variables, which can not be determined by the R script only. Maybe you can write a tool by yourself to parse the R syntax to resolve your problem.

a C/C++ file that I can be used by gnu make. I'm wondering if there is
a tool that can generate dependence file for an R script.
For example, I have an R script test.R
#########test.R
load('input.RData')
save.image('output.RData')
I want to generate a dependence file like the following. Is there a
tool to do so?
output.RData:test.R input.RData
Is there a way to automatically generate the output files that depends on an R script and the input files and sourced files that are depended by an R script? I don't see this option in R. But I wish this can be implemented in future version of R.
