rearrange data columns
Dear R users,
I need to to the the following. Let a= 1 2 3
4 5 6
and b= -1 -2 -3 be (2x3) matrices.
-4 -5 -6
I need to combine the two matrices into a new (2x6) matrix like this:
ab = ( 1 -1 2 -2 3 -3 )
4 -4 5 -5 6 -6
How can this be done in R?

trellis margin sizes in absolute units
Dear R users,
I have a lot of experience with traditional R graphics, but I decided to turn to trellis as
it was recommended for spatial graphs by the sp package. In traditional R graphics
I always first set the size of the device region absolute units (e.g. mm) and then I
firmly fix the inner margins with mai and the outer margins with oma also in absolute units.
What is left from the device

a question on impulse responses
Dear R users,
I am using the vars package to calculate the impulse response functions and the forecast error variance decomposition of a VAR model. Unfortunately I do not know whether these functions assume unit or one standard deviation shocks. I tried to look into the code of these functions, but in vain: neither irf, nor vars::irf, nor vars:::irf output the code of the functions. Does someone

calculate impulse responses
Dear R users,
I need perform structural analysis on a no intercept VAR model. Unfortunately the functions irf.VAR and dfev that come with the MSBVAR package only work with objects output by the reduced.form.var function, which seems to only evaluate VAR models with intercept. Is there a way to suppress the estimation of intercept term in reduced.form.var? Do I need to modify the code, and if I

A question on type="h" plot lines
Dear R users,
I need a produce a plot with a single panel and a few lines on it. Each line represents a different data set. The line types must be "h", i.e. ?histogram? like (or ?high-density?) vertical lines. The problem is that the vertical lines comprising a plot line of type="h" are drawn from the y=0 line to the (x, y) locations. What I need is vertical lines drawn from

tcgetattr: Inappropriate ioctl for device
Dear nut users,
I am running nut-2.6.0 on Slackware-Linux-13.37.0 with kernel 2.6.37.6.
I am trying to get the software work for a repotec UPS with model name: RPT-1003AU. The UPS communicates with the computer via USB. I know that the model is not officially supported but I want to try out whether it will work with some of the repotec drivers. Here is the result with the genericups upstype=13

biplot from stats: 0.8 ?
Dear forum,
I need to create biplot graphic. I took a look at the code of the biplot.default function from the stats package and I found that the arrows for the variables are multiplied by a coefficient of 0.8 before plotting:
...
if (var.axes)
arrows(0, 0, y[, 1L] * 0.8, y[, 2L] * 0.8, col = col[2L],
length = arrow.len)
...
I have no idea why this is done. Could somebody

problem with abline and lines
Dear R users,
I need to plot to perpendicular straight lines. However, although I set the coefficients
so that the lines are perpendicular, they do not look to be so in the plot. Here is a minimal working example:
plot(x=c(-1, 1), y=c(-1, 1)); abline(a=0, b=1/sqrt(2)); abline(a=0, b=-1/sqrt(2))
Please tell me if the same problem is valid by you. I am running R-2.10.1 on Linux.

get: problem with environments
Dear R users,
I am running R-2.15.1 in Linux Slackware64-14.0. Here is my minimal working example:
testfun <- function (x) {
a <- 0;
sapply(X="a", FUN=get, envir=sys.frame(which=x));
}
Inside R, that is R called from within a Linux terminal, the following code works:
testfun(x=5)
print(testfun(x=6))
But within rkward the above code fails and the following works:

powercom UPS shoutdown discussion
Thank you for your response.
The point is that I have configured my system to shut down at the event "upsc Inform@localhost ups.status"!="OL", not at "LB". So there will be no /etc/killpower file created. At an ups.status != "OL" event, the following script named "notifyme" is run:

Fwd: MDS problems [ajtee@ajtee.uklinux.net]
Hi all,
I'm trying to perform an MDS of some data that I have. When I use
cmdscale everything is fine and I get some interesting results however,
the tends to be low.
What I wnat to do is compare this with the Non-Metric MDS using isoMDS
or sammon. However, when I try using these I get the following message.

Set quota on Lustre system file client, reboots MDS/MGS node
Hi
I used lustre-1.8.3 for Centos5.4. I patched the kernel according to Lustre

I have a problem when I want to implement quota.
My cluster configuration is:
