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? Many thanks, -tom -- ------------------------ tomfool at as220 dot org http://sgouros.com http://whatcheer.net
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.
This is hack which may need to be modified if the internals of the
source command change.

(Or ODFweave, etc.) These allow you to mix R code right into a document that explains the reasoning and includes both the input and output of the script. Duncan Murdoch

(Or ODFweave, etc.)Thank you, that is pretty marvelous. I will use it next time around. -tom -- ------------------------ tomfool at as220 dot org http://sgouros.com http://whatcheer.net
