I'm trying to index the word "peter-bengtsson" (which is different from "peter" & "bengtsson" and is different from "peterbengtsson") and find it. To start with I'm trying to use a basic python script to get to grips with it. When I do this:: qp = xapian.QueryParser() stemmer = xapian.Stem(&q...

Thanks, this was what I expected. There is a desire to eliminate the usage of pairlist from user code, which suggests the alternative of allowing for function arguments to be stored in lists. That's a much deeper change though.

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back

I am aware of one (unofficial) guide to style for R programming: http://www1.maths.lth.se/help/R/RCC/ from Henrik Bengtsson. Can anyone provide further pointers to good style? Views on Bengtsson's ideas would interest me as well.
