Subsetting simulation output
Does anyone understand this?
I have a long vector parlist containing values of 138 parameters in 100
simulations.
The factor parno is defined by
trys <- 100
sim <- gl(trys,138)
parno <- gl(138,1,trys*138)
I want to extract and compare results for related groups of parameters but I
get inconsistent results:
> length(parlist[parno==37:42])
[1...

PLEASE, can we fix this!
Idea: don't shorten the `parlist' argument of GetPar(),
for efficiency.
Just set the TAG to "", such that it will be disregarded subsequently,
i.e., do something like
SEXP GetPar(char *which, SEXP parlist)
{
SEXP w, p;
w = install(which);
for (p = parlist; p != R_NilValue; p = CDR(p)) {
if (TAG(p...

non linear regression with nls
Hello,
I'm a beginner with R and it's the first time I'm using the R-help list... I hope I'm in the right place, if not:
Sorry!!
I need to do non linear regressions on a data set which columns are:
"river.name" "Portata" "PTG.P" "PO4.P" "NT.N" "NH4.N" "NO3.N" "BOD5" "SiO2"

WISHLIST: on.exit(..., add=TRUE, where="first") to address common use cases
Before trying to submit a patch(*) to on.exit(), I'd like to check
whether there is an interest in enhancing on.exit(..., add=TRUE) such
that it is possible to specify whether the added expression should be
added before or after already recorded expression. The default is now
to add it after, but it would often be useful to add it before
previously recorded expressions.
EXAMPLE:
foo <-
