How do I run system executables with aliases within R?

Question

Suppose, I am running system command in R to run an executable.

inputfile <- \"/path/myfile.txt\"

How can I replace /path/myf

Answer 1

Try either of these:

library(gsubfn)

fn$system("executable -input $inputfile  -output output.txt")

or without packages:

cmd <- sprintf("executable -input %s -output output.txt", inputfile)
system(cmd)
