Get the path of current script

by

In RStudio, you can get the path to the file currently shown in the source pane using

rstudioapi::getSourceEditorContext()$path

If you only want the directory, use

dirname(rstudioapi::getSourceEditorContext()$path)

If you want the name of the file that’s been run by source(filename), that’s a little harder. You need to look for the variable srcfile somewhere back in the stack. How far back depends on how you write things, but it’s around 4 steps back: for example,

fi <- tempfile()
writeLines("f()", fi)
f <- function() print(sys.frame(-4)$srcfile)
source(fi)
fi

should print the same thing on the last two lines.
