coercing created variables into a new data frame using na.omit()
Hi,
I am an R newbie and one thing I am having trouble with binding variables that
I have created within one data frame into a new data frame when using
na.omit(). To illustrate this problem I will give the example I am working on
and the approah I have been using:-
data.frame1<-filepath....
attach(data.frame1)
#create a new variable using a function
new.variable<-rep(1,length(weight3))

Weighted densityplot?
I'm trying to plot a series of densities using/comparing differing weights. I see the reference to weights and subscripts, but I don't understand how to implement that. My data are of the form:
I, J, Actual, Distance, Subset, Weight1, Weight2, ...
I'm trying to see the effect of the distance distribution (Actual by Distance) compared to the various weighted distributions

Problem in using rsync
Hi
I use rsync to perform backup on disk on a SunFire 880 with Solaris 8. For
performance issues, we launch simultaneously 5 rsyncs on 5 different fliesystems
and about 150-200 "cp -p" commands on as many database files. We have been
using the same scripts for about 2 months, without problems. The backup is
performed on the same server (from filesystem to filesystem on the same

Exporting interactive 3D plots with axes and labels

I have a question about exporting interactive 3D plots. I use the following code to plot a contour of a trivariate normal distribution:

Names of data frame columns in an apply
Hi,
[some background]
I have a dataset which describes a number of subjects doing a "scientific
discovery". That is, they have to discover the rules underlying a
particular domain. To do so, they have to set the levels of 5 variables
which leads to a certain outcome. To identify what kind of "experiments"
the subjects did, I want to combine these levels into one variable

nls() newbie convergence problem
I'm sure this must be a nls() newbie question, but I'm stumped.
I'm trying to do the example from Draper
and Yang (1997). They give this snippet of S-Plus code:
Specify the weight function:
weight < - function(y,x1,x2,b0,b1,b2)
{
pred <- b0+b1*x1 + b2*x2
parms <- abs(b1*b2)^(1/3)
(y-pred)/parms
}

read.spss doesn't work anymore
A couple of months ago, probably using an older version of R, R used to
run the following code just fine:
library("foreign")
data.exp1 <- as.data.frame(read.spss("dataDef.sav"))
Issuing the same commands now (after starting R using --vanilla), gives
me the following behavior:

ssh-keyscan: xmalloc out of memory error
hi all,
I got "xmalloc: out of memory" when i used
ssh-keyscan to a remote host that is using
SSH protocol 2 and only protocol 2 (no fallback
to SSH protocol 1).
Looks to me more like ssh-keyscan doesn't talk
SSH protocol 2 to the server.
Please help.
Here is the exact error:
