to combine bwplot + srt option?
Hi R-users,
Could someone help me to combine bwplot and srt option (exemple srt = 45
degree or srt 90 degree)? My graphic contains 146 boxplots, I would like
to label all of them. As you know, labels are not readable.

Troubleshooting with "gpd" (Fit generalized pareto model)
Up to now, I have recognized problems with "gpd(..)", the function from
the package "evir"
I think that all these functions that estimate the parameters xi, beta for
the GPD
by given threshold mu use the function "optim(..)" ( gpd, fitgpd, ...)
"Error" example:
data1 <- rgpd(1000, xi= -1.5, mu=1000, beta=100)

loop for plot function
Hello all R users,
I would like to add another loop to my following R code ( it works for the
moment correctly) , which will be able to me to vary n (see the code) from
1 to 4 or 5.
And I also would like apply the plot function in this case, eg all four or
five figures in the same graphic (n= 1, 2, ..., 4 ou 5)
I have tested one, but unsuccessfully.
I need you to solve this problems
Thank you

DOE and interaction plot general question
This is a general question about Design of experiments. If i am not allowed
to post general questions like this here please accept my apologies and
ignore the question.
I did a DOE with six factors in eight runs. I know i cannot check for
interactions using this design, but i tried the interaction plot and it
showed me many interactions. After this I foldover the design and ran the 8

adding overall constraint in optim()
Hi ?
This is giving me a headache. I?m trying to do a relatively simple optimization ? actually trying to approximate the output from the Excel Solver function but at roughly 1000x the speed. ?
The optimization parameters look like this. The only trouble is that I want to add a constraint that sum(wgt.vect)=1, and I can?t figure out how to do that in optim.

Subsetting vectors based on condition
Hello,
I have a question regarding subsetting of vectors. Here's an example of
what I'm trying to do:
vect.1 <- c(76,195, 290, 380)
vect.2 <- c(63, 95, 133, 170, 215, 253, 285, 299, 325, 375)
I would like to subset vect.2 so that it has the same length as vect.1,
and its numbers are the first corresponging higher value compared to
vect.1.
The output should be:

Vector indices and minus sign
Hi,
I got caught out by this behaviour in 1.8.0 and I wondered why this
happens:
I have a list of vectors and was using lapply and grep to remove
matched elements that occur in only a subset of the elements of the
list:
locs <- lapply(locs, function(x){x[- grep("^x", x)]})
The problem is that where the grep finds no matches and hence returns a
vector of length 0, all the

adding overall constraint in optim()
Thanks Bert. But everyone on that forum wants to use finance tools rather than general optimization stuff! And I am not optimizing a traditional Markowitz mean-variance problem. Plus, smarter people here. :-)
