Maybe I could (and should?) have defined the class with just one slot that
contains the list, which would make it behave like I want it immediately.

Does that mean, then, that the help page's "x$name" just accidentally coincides
with the arguments x and name that the "$"-function requires in S4?

Dear R-help crowd,
is it possible to specify a time delay for plotting the points in a curve? I
would like to make the plotting process slow enough to show the development
of the graph, and therefore I am looking either for the possibility within
the plot function to specify a plotting speed or

I think that there is an understandable wish to have the simple orthogonal
plans (and be it only for non-experts to be able to analyse the results
themselves). For mixed levels, there is e.g. the L36 that should be able to
accomodate plans like 2x2x2x3x3x3. Unfortunately, R is not very strong in

I am trying to wrap up a package "utilities" (for my internal use). After
adding a function datNAtreat that uses mapply, R CMD check gives WARNINGs

and "checking foreign function calls", all of which are accompa
Sorry, just pressing the send button brought the solution :-)
The problem has nothing to do with any programming issues, but rather with
confusion about directories to use R CMD from.

Dear helpeRs,
I have a column of various different entry types denoting missing value codes
for a data frame. Elements can be numbers (e.g. 9), combinations of numbers
e.g. in the form c(0,9,99), or NULL (for no valid missing data code).
I used
codes<-read.table(paste

d by the way, as you are using hier.part, you might also be interested in
the package relaimpo (linear model with R-squared only, but more different
metrics for partitioning).

Dear useRs,
I may be temporarily (I hope :-)) confused, and I hope that someone can
answer this question that bugs me at the moment:
In the CP table of rpart, I thought the following equation should hold:
rel error = rel error(before) - (nsplit - nsplit(before)) * CP(before),
where (before
The down side to R's factor solution:
The numerical values of factors are always 1 to number of levels. Thus, it
can be tough and requires great care to work with studies that have both
numerical values different from this and value labels. This situation is
currently not well-supported by R.
