If the data is not confidential, it might be a good idea to load a sample of it

I get the following error when I try to modify the names of the object
returned by get(). Does anybody know how to do so? (I could use as.vector()
to remove the names, but I'm interested in how to modify the object returned
by get().)
$ cat main_get_name_assign.R
x=1:10
names(x)=letters[1:10]

The try this:

Hi All,
I have been experiencing a strange issue ever since I upgraded my R and the
packages. I cannot plot anything to the CairoPNG device.For an example:>

dev.off()will create an empty plot.png file. I am running R 2.12.1 (

I'm quite new to R but tried to learn as much as possible in the last

Dear all,
I am stuck the reading of a file which has 100s of rows and variable column
counts.
The tab-limited data file looks something like:

Some_Taxt 131331434-2191010178
Some_Tsxt 132441334
First I have read all the previous post on error bars & segments as well as the
Lattice book by Sarkar.
I am using xyplot, there are 2 panels, each panel displays the measurements
from 5 matrices over time. The matrices are identified by different colors.
My error bars show up in the 1st
Dear Eduardo,

Colin,
If your propose is to create a ternary plot with points and vectors, I think
easier do this with graphics based plots instead of trellis based plots.
Although, with little work you can do with trellis too. I gave you a
reproducible code to put an arrow in a ternary plot. I use the funct

Hi
I am attempting to convert my simple weighted regressions (produced using the
weights argument in lm) to a constrained regression where the coefficients sum

Hi guys,
I have been testing the hypothesis for difference of survival between four
different classes. The p-values provided in coxph output are confusing for me
to interpret.
Here is the output :
sur<-coxph(Surv(SURVIV, status == 1)~factor(A)+cluster(rownames(d)), data = d,
model=TRUE)

Thank you very much Greg,
This was helpful.
With yaxs="r" I can easily obtain the Y-axis labels with :
rg <- range(y) + 0.04 * diff(range(y)) * c(-1, 1)
pt <- pretty(y)
axTicks(side=2,
usr=c(0, 1, rg),
axp=c(min(pt),
max(pt[pt <= max(rg)
This is handled simply with an AND operator. You use a mask the size
of the counter:

Dear Mario,
See: http://www.mail-archive.com/r-help@r-project.org/msg117622.html
This seems to be fixed in version 2.12.1 (at least, I do not get this problem
anymore).
Best,
Wolfgang

You can also create a local copy of 's' in the function:
