If what you mean is that you have a file, test.R, of R commands
and you are using source("test.R") and you wish to discover the
name "test.R" without hard coding it in your file, then place this in
test.R:
ofile <- parent.frame(2)$ofile
and ofile will be set to "test.R". Note that the line shown should not
be within a function or other local environment within the file but
directly at top level.
Thank you, that is an excellent hack, and I will use it carefully (though often), but it isn't quite what I had in mind. In my script called test.R, there is a function called "survey.write", which writes a report based on some survey results. It is called several times at the top level. I would like the report to say how "survey.write" was invoked, whether it was invoked as "survey.write(res.raw,res.q)" or "survey.write(bus.raw,bus.q)". Obviously I have access to the values of the arguments, but I want the names of those arguments, or a string containing it all. Thanks, -tom
This is hack which may need to be modified if the internals of the source command change. On Dec 2, 2007 6:24 PM, Tom Sgouros <tomfool at as220.org> wrote:
Hello all: I have a function that writes a fairly elaborate report based on some survey data. For documentation and bookkeeping purposes, I'd like to write out in the report the function call that produced the report, or at least enough information to help me recreate the steps that led to that report. I've been generating all the reports with scripts, in order to be able to recreate the steps, but apart from the file name, I don't yet have a way to match the report to the script that created it. Can anyone suggest easy ways to do this? From within a function, is the function call text available somehow, or the names of the arguments used in the function invocation?
