Hi Jim,
You could also use the 'select' argument. For example,
plot(gam.object,se=TRUE,select=1)
will give you the smooth plot for the first variable.
Be sure to read the documentation. See ?plot.gam for specifics details on
plotting gam objects.

?plot.gam or ?preplot.gam says there is an ask= option, slightly bizarrely set
to F by default.
If ask=T, You'll get a menu of options for plotting. In windows, hitting "Esc"
will get you out of the menu.
example:

Hi, All,
I am a beginner for R. Now I have installed R 2.5.1 in Window

Any time you are calling a function one value at a time,
it is worth asking if you can eliminate a loop (or more).
If 'G.fun' is vectorized in its first argument, then you can
easily get rid of the three inner loops. Just generate a
vector of all of the values and do:

Hi,

G <- rep(NA,n)
for(i in 1:n)

{
for(m in 1:n)
{
gj <- gj+G.fun(XB[i]+p[3]*X[j,3]+p[4]*X[l,4]+p[5]*X[m,5],ff)
}
}
}
G[i] <- gj/n^3
}
Thanks.

Most likely the file lahore.txt isn't in the current working
directory, which is where R will be looking for it as you don't
specify a path (I'm assuming that you are working in Windows). If so,
you have three options. 1) Move lahore.txt to the current working

Move to the appropriate directory first (or else move your

file to that spot.
3. Another possibility is:

Not so long ago, I quickly glan
Greetings,
Sorry for the basic question, but I am trying to find out if R is a suitable
platform for what I want to do...
I am interested in creating simulations of distributed algorithms (i.e. team
formation, Byzantine Generals , P2P communication modeling, mobile networks)
that would be

I think this is not a R-devel question. Sorry to all if I'm wrong,
please let me know.
I managed to build R successfully with the default BLAS but when I
change the MKRULES to use ATLAS BLAS and set the path to
"C:/cygwin/home/Administrador/ATLAS/lib/WinNT_ATHLONSSE2" I got the
following error mes
Thank you so much Marc.
Your solution is exactly what I am looking for.
Have a nice weekend.

let us know what you want to do because the beauty of R is that, in many
cases, you may not have to loop.

Two options:
x <- c(0.1, 0.5, 0.6)

Dear Lister,
If I have a list of number, say x<-c(0.1, 0.5, 0.6...), how to use a for()
to loop through each number in x one by one?
Thank you so much!

Dear R Users,
Did someone implemented the R1 (Pseudo R-2) and likelihood ratio
statistics for quantile regressions, which are some of the inference
procedures for quantile regression
found in Koenker and Machado (1999)?
I tried the Ox version, but my dataset is too large (> 50.000) and the
