gam and ordination (vegan and labdsv surf and ordisurf)
I have a general question about using thin plate splines in the surf
and ordisurf routines. My rudimentary knowledge of a gam is that with
each predictive variable there is a different smooth for each one and
then they are added together with no real interaction term (because
they don't handle this well?). Now, If I have two variables that
have a high D^2 score and a low GCV score (I am

Stacking Vectors/Dataframes
Hello,
Is there a simple way of stacking/merging two dataframes in R? I want to
stack them piece-wise, not simply add one whole dataframe to the bottom of
the other. I want to create as follows:
x.frame:
aX1 bX1 cX1 ... zX1
aX2 bX2 cX2 ... zX2
... ... ... ... ...
aX99 bX99 cX99 ... zX99
y.frame:
aY1 bY1 cY1 ... zY1
aY2 bY2 cY2 ... zY2
... ... ... ... ...
aY99 bY99 cY99 ...

plotting other axes for PCA
Hi R-community,
I am doing a PCA and I need plots for different combinations of axes (e.g.,
PC1 vs PC3, and PC2 vs PC3) with the arrows indicating the loadings of each
variables. What I need is exactly what I get using biplot (pca.object) but
for other axes.
I have plotted PC2 and 3 using the scores of the cases, but I don't get the
arrows proportional to the loadings of each variables on

print table on plot
Hello,
I would like to be able to plot an array on a plot, something like:
|arg1 | arg2 | arg3
val1| 0.9 | 1.1 | 2.4
val2| 0.33 | 0.23 | -1.4
val3| hello| stop | test
I know Rwave is good to report but don't want to use it.
? Is there a package that allow quick and dirty plot of dataframes like this
?
Thanks a lot

simulating stable VAR process
Hello all,
I looking at package dse or vars or mAr
I know how to simulate a VAR(p) process, my problem is that most of those
processes are unstable (not weakly stationary).
Do anybody know how to generate a random VAR (or VARMA even better) process
that is weakly stationary?
Thanks

Count number of rows in a matrix with a character pattern
Hi,
I have a large data set that I input as a matrix, where I have 1:x rows
with names AX, then x+1: y rows named AY, etc. The idea is that I have to
count how many rows exactly I have with name AX and how many I have with
name AY (or find which row numbers have names AX). Is there any way in R to
count a number of rows with a name matching a required pattern?
Thanks in advance,

2. the time as the number of milliseconds elapsed since hour 00:00:00.000 of
this date.
My question is :

object for instance) from what I have ?

I have downloaded the newest source code ocfs2-1.2.3.tar.gz from

After do the configuration I find a strange thing. Although my
kernel is "2.6.9-11.19AX"(Asianux2.0 on a vmware server with a single
processor configured), the configuration find that it is
2.6.9-11.19AX-smp. So after I make and install, those *.ko went to the

function in order to plot the same graph to postscript and pdf
Hi,
I've written a function in order to plot the same graph in a postcript and in
a pdf file. Unfortunately, the second graph is always empty, i.e.:
plot.both <- function{myplot, filename}{
pdf(file=paste(filename, ".pdf", sep=""))
myplot
dev.off()
postscript(file=paste(filename, ".eps", sep=""))
myplot
dev.off()

Save generic plot to file (before rendering to device)
I am looking for a way to save a plot (graphics contents) to a file after the
plot has been calculated but before it has been rendered. More specifically,
assume that I made a plot that took a very long time to produce, I would
like to save this plot to a generic file that I can later, on a different
machine, render to either PDF, PNG, SVG using the usual R graphics devices,
without recalculating

help with formula and data= argument
Sorry for posting this twice, but I still have not solved this problem

to the user providing a formula (with a data= argument) or not (similar
to plot(x,y) versus plot(y~x,data=data)). I have found a method to work
with this in a simple case but am having trouble determining how to
