grouping in scatterplot3d
Hi all,
I've been using the scatterplot3d function (from the scatterplot3d library) to create 3D plots. I was wondering whether there is
anyway to group the points according to a particular group variable. For example I used the plot function as
plot( factor( <GROUPINGVAR> ) , <PLOTVARS> )
to organise the results in a according to the grouping variable. I was wondering

overriding "summary.default" or "summary.data.frame". How?
I suppose everybody who makes a package for the first time thinks "I
can change anything!" and then runs into this same question. Has
anybody written out information on how a package can override
functions in R base in the R 2.14 (mandatory NAMESPACE era)?
Suppose I want to alphabetize variables in a summary.data.frame, or
return the standard deviation with the mean in summary output.

Adding RcppFrame to RcppResultSet causes segmentation fault
Hi,
I'm a bit puzzled. I uses exactly the same code in RcppExamples
package to try adding RcppFrame object to RcppResultSet. When running
it gives me segmentation fault problem. I'm using gcc 4.1.2 on redhat
64bit. I'm not sure if this is the cause of the problem. Any advice
would be greatly appreciated. Thank you.
Rob.

nlme Error: Subscript out of bounds
Hello, I am new to non-linear growth modelling in R and I am trying to
reproduce an analysis that was done (successfully) in S-Plus.
I have a simple non-linear growth model, with no nesting. I have attempted
to simplify the call as much as possible (by creating another grouped
object, instead of using subset= and compacting the fixed and random
expressions.)
This is a what the grouped

Speeding up lots of calls to GLM
Dear useRs,
First off, sorry about the long post. Figured it's better to give context
to get good answers (I hope!). Some time ago I wrote an R function that
will get all pairwise interactions of variables in a data frame. This
worked fine at the time, but now a colleague would like me to do this with
a much larger dataset. They don't know how many variables they are going to
have in the
