Dear All, I am new to R and can see it is a very powerful and versatile system for programming and statistical analysis. Say I have written a simple function and want to use it on a regular basis. I have the file as a text file say 'c:\R-funcs\func.txt' how do I get R to find it on the hard disc or alternatively where is the default location for looking up functions where I can place this file. eg where are functions such as var(), mean() etc stored? At the moment I'm pasting the text of the function into the GUI prompt, not very satisfactory if it is to be used in a programme. Please forgive any naivety on my part as I am just starting out Many thanks in advance Guy ---------------------------------------------------------------------- Guy J.

maybe

does the trick?

They you can use library(mypackage) to make them available. But creating a package on Windows is not for absolute beginners.> At the moment I'm pasting the text of the function into the GUI prompt, > not very satisfactory if it is to be used in a programme. > > Please forgive any naivety on my part as I am just starting out > > Many thanks in advance > > Guy > > > ---------------------------------------------------------------------- > Guy J.
