Sv: Sv: Ordinal Regression
Dear Peter.
I guess you know that Jim Lindseys code include nordr and ordglm in library gnlm - I attach the htmls which do various linear and nonlinear ordinal regressions - exemplified with just the data mentioned, McCullagh (1980) JRSS B42, 109-142. I had it work very fine.

RegExp Question
I have to admit that I'm a bit ignorant about
regular expressions...I have a problem with "gsub":
under unix I can :
> cat tmp.txt
F.123 F.123
F123 F123
sed 's/F\./d/g' tmp.txt
d123 d123
F123 F123
that is: replacing "F.", however under R:
gsub("F\.","d",c("F123","F.123"),extended=F)
[1] "d23"

g'day R friends,
can anyone please help me with a frustrating merge?
The number of rows of a resulting merge is the smaller of the 2 dataframes

multiple lattice-pages (development package!)...
One Question: if I make a lattice-plot (beware: under development!) with
a special layout e.g. c(2,2,4):
p1 <- xyplot(y~x|id,data=data,layout=c(2,2,3))
is there a way to print.trellis e.g. the second page of the trellis
object "p1"?
print.trellis(p1,page=2) #!wrong!
I want this to automatically dev.print the pages (no, I don't want multiple
postscript pages). If this

lattice (!under development!) font curiosity
Perhaps this might be a font problem, it might be that my font dirs
are broken (but I don't think so, it is a standard potato inst.):
> xyplot(rnorm(10) ~ rnorm(10) ,main=list("???dsa",cex=2))
...displays German special characters false (as greek letters).
Curiously these work o.k.:
> xyplot(rnorm(10) ~ rnorm(10) ,main="?dsa")
> xyplot(rnorm(10) ~ rnorm(10)

Landscape problems with ps2pdf [summary]
Since I sent my original question last week, this is one of two suggestions
that worked. Using Adobe Acrobat, as suggested by Professor Ripley, was
very satisfactory, but required that I use multiple platforms to make the
conversion to PDF (from Linux to Windows).
The solution by Peter Adorjan (included below), also worked very well, and
can be carried out on any platform using tools available

qt with ncp?
Does anybody has a function or idea how to calculate qt with a noncentrality
parameter? I'm porting a SAS-macro for equivalence (Wellek, 1994 TT2ST) to R
and it seems that I need this to calculate tinv (SAS-command, I hope that
this is R's qt,...I get the SAS-macro manual next week).
thanks

? Nice colors for lattice?
Just a quick question: Does anybody has a nice palette (
yes, I know that this isn't the right lattice-command) for lattice?
I'm just making some graphs for a poster-presentation and I'm don't really
like these trellice colors.
Thanks

Excluding rows from a matrix
Hi
I have a matrix (4 x 950) and I want to remove 3 rows, where the values
from the first column are 713, 714 and 715. I can select the rows, one
by one, with
mat[mat$first==713,]
mat[mat$first==714,]
...
but I'm unable to (i) select the 3 rows at once, (ii) select the matrix
excluding those rows.
How can I do it ?
Thanks

by & tapply
Rers,
I have been using the function 'by' in such a manner:
by(LogMetric, list(Loci.Number=Loci.Number, Code.Flag=Code.Flag), plot)
with
par(mfrow=c(5,3))
to produce a single R Graphics: Device with 14 different plots on it as
described above in my 'by' statement. Thank you for helping me thus far.
A similar command using 'tapply' can be written as well.

R with ESS: how to start
I installed ESS but I can't figure out what needs to be set
for it to recognise R. I gather it's something to do with
.emacs file, but none of the help files seem to mention it.
Like everything, it's probably easy once you know, but so
far I don't know where to look.
Thanks for any help.
best
