I was glad to see the new rpart.plot package by Stephen Milborrow. I was however a bit concerned that Stephen distributed a dataset I created, and renamed the dataset (from titanic3 to ptitanic) in the process [with some justification, as some variables were omitted]. Fortunately Stephen included the script he used to download the dataset from our web site, and...

Greetings R developers, R will run a little faster when executing "pure R" code if the function R_CheckStack() is modified. With the modification, the following code for example runs 15% faster (compared to a virgin R-2.5.1 on my Windows XP machine): N = 1e7 foo <- function(x) { for (i in 1:N) x <- x + 1 x }

...nb) ab[i + j] <- ab[i + j] + a[i] * b[j] The loop will run about 30% faster. That's not much of a speedup, but the code is still in early development and the figure will get much better. If you are interested there is more information at www.milbo.users.sonic.net/ra. Stephen Milborrow www.milbo.users.sonic.net

Some already know, but I think it deserves a bit of a attention here as well: It looks like we're about to get new features in R that will be very powerful! That should be a good enough teaser for now... /Henrik PS ...and thanks for making it available plus credits to similar efforts by others.

...bo.org/postscript/slow-postscript.R This is not exactly a bug, but is it a known issue? The hack used to produce fast.ps above is fragile and not suitable for regular use. Is there a option to the postscript() function (or could one be added) that would sacrifice sRGB support for speed?

While I'm very pleased with the results I get with rpart and rpart.plot, I would like to change the scientific notation of the dependent variable in the plots into integers. Right now all my 5 or more digit numbers are displayed using scientific notation. I managed to find this: http://tolstoy.newcastle.edu.au/R/e8/help/09/12/8423.html but I do not fully understand what to change, and to

It appears to be legitimate to include multi-level categorical and continuous variables in defining the model for earth (e.g. y ~ cat + cont1 + cont2) but is it also then possible use categoricals in the predict method using the earth result? I tried but it returns an error which is not very informative. Thanks Chris

Not possible in the current implementation. In principle it would be possible to extend earth so the user-defined "allowed" function
