Dear R-Developers, The traffic today on s-news where Terry Therneau, I, and others are reporting some of the problems we have had using or converting applications to SV4 reminded me of something Duncan Temple Lang had mentioned to me a year ago that I wanted to follow up on. I recall that Duncan said either that if SV4 were to be implemented in R that it would not be the default behavior, or that through an option the new behavior could be turned off. Would you m...

I don't have a copy of SV4 (or SV3, where model.frame was introduced), but S+ 8.3 (based on SV4) puts the class "model.frame" on model.frame()'s return value but has no methods (in the default packages) for class "model.frame". Perhaps that is why R omitted the class. However, S+ 8.3's (and prob...

Is there a reason that model.frame() returns a data.frame with extra attributes but no special class or is it just an oversight?

Hi all, Was wondering if any body would know if the book "Programming with Data" a guide to S language could be used as a guide to working with the R language. Comments, suggestions, a book review is welcomed. Thanks Josef Bohart -------------- next part -------------- An HTML attachment was scrubbed... URL:

Does R, or will R, be integrating the changes to the Chambers/Lucent S language under their version 5.0? If not already, then when?

R-helpers: I have a dataset that has 168 subjects and 12 variables. Some of the variables have missing data and I want to use the multiple imputation capabilities of the "mice" package to address the missing data. Given that mice only supports linear models and generalized linear models (via the lm.mids and glm.mids functions) and that I need to fit Cox models, I followed the previous

I have been writing quick and dirty S-plus code for years, but for a recent project I took the plunge, bought Venables and Ripley's S Programming, and implemented a class library using new style classes (in S-Plus 6.0). It worked quite nicely and I am wondering about making more routine use of them. Before I make much more of an investment, I have a few questions, both factual and subjective,

I think this goes back to SV4 (c. late 1990's). The is.<type> functions are much older (c. mid 1970's) , from before any class system was in S. is() and inherits() were introduced with the S4 class system and were meant to escape from the prison made by ancient design choices.

Hi all, Does there already exist a version of substitute that evaluates it's first argument? (i.e. it accepts an already quoted expression). This seems like something that's pretty handy, but I haven't found any existing function to do it: substitute_e <- function(expr, env) { eval(substitute(substitute(expr, env), list(expr = expr))) } f <- quote(x + y + z) substitute(f,

...acked in a New Zealand court and I doubt that they would be particularly sympathetic to Mathsoft. John Chambers has told us that he is sympathetic and supportive of R development and has often discussed internal details of S with us. At the last Interface meeting he was asked whether he might make Sv4 "free". He didn't completely rule it out, but I think the recent Mathsoft/Lucent agreement does. I think that John faces a real conflict. He is at heart an academic researcher, but his work environment has become increasingly commercial and has driven him in a direction he is not e...
