how to store the response of a system call from R studio to Mac OS X

Not sure how to best ask this. I want to store the response of a system command in R studio Mac.

For example, this command:

system("pwd")

Returns this: 

/Volumes/chart/chart

I would like to store the return in a variable like this:

result <- system("pwd")

but this does not work.

Solution

  • Use the intern parameter.

    result <- system('pwd', intern = T)
result
#> [1] "/Volumes/chart/chart"
