SV4 on R?
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...

formula(model.frame(..)) is misleading
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...

> m0 <- model.frame(data=d, Y ~ A:B)

Y ~ A:B
This is in part because model.frame()'s output has class "data.frame"
instread of c("model.frame","data.frame"), as SV4 did, so there are no
methods for model.frames.
Is there a reason that model.frame() returns a data.frame with extra
attributes but no special class or is it just an oversight?

will book on S plus help understanding R ?
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

MICE for Cox model
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

Old style and new style classes
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,

Discrepancy between is.list() and is(x, "list")
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.

Version of substitute that evaluates it's first argument
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)

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...
