Send code to R from WinEdt55
R Gurus:
This sounds not a FAQ. I upgraded WinEdt from 5.4 to 5.5 ,
following load RWinEdt, R-WinEdt editor appears. There are more menu
items and task icons in this version, but I failed to find a pull down
menu or task icon to send code to R.
What did I miss?

lattice::panel.levelplot.raster too picky with unequal spacing
Dear all,
I got a couple of warnings using panel.levelplot.raster,
In panel.levelplot.raster(..., interpolate = TRUE) :
'y' values are not equispaced; output will be wrong
although I was quite sure my data were equally spaced (indeed, I
created them with seq()). A closer look at the source code reveals
that the function tests for exact uniformity in grid spacing,

blank pdf output when called in a loop
Hi,
I'm hitting a strange problem where pdf plots that I'm trying to make
are blank, only when produced from within a loop. The pdf contains 0 page.
I've narrowed the problem to this minimal script that invariably
produces an empty pdf with my setup:
pdf("/local/scratch/1.pdf", width=8, height=8)
for (k in 1) {
wireframe(volcano)
}

Can't load "doSMP" from REvolutionR in regular R2.11.0
Hi list,
I was testing out the "doSMP" package from REvolutionR in my regular R2.11.0 installation and I got the following error message.? Well, one obvious thing is that R2.11.0 was built using "i386-pc-mingw32" which is different from what revoIPC used.? I could just use REvolutionR, but all my R peripherals were set up to work
with the regular R2.11.0.? So, I really want

Passing data to aov
Hello Again Gurus and Lurkers:
I?m trying to build a very user-friendly function which does aov without
having the user type in a formula (which would be tedious in this case).
The idea is to take the response from a PCA score matrix, and the factors
from a list. A simple example is the function given below, along with test
data and a sample call to the function.
I'm certainly having

Non-zero exit status for survival package
I'm running R 2.11 on Karmic. I'm having difficulty installing quite a
few packages with the returned error message of "installation of package
"[whatever the packages happens to be]" had non-zero exit status. I know
this message sometimes is caused by incorrect or missing java packages
and the like. I generally don't have issues with the installation of R

Specifying interactions in rms package... error
I am encountering an error I do not know how to debug. The error arises
when I try to add an interaction term involving two continuous
variables (defined using rcs functions) to an existing (and working) model.
The new model reads:
model5 <- lrm( B_fainting ~ gender+ rcs(exactage, 7) +
rcs(DW_nadler_bv, 7) + rcs(drawtimefrom8am, 7)+ DW_firsttime+

Dynamically build variable names
I'm trying to dynamically build variable names to use on a list. Let's say I have a list like this one:
l <- list(V1_1=c(1,2,3), V1_2=c('One','Two','Three'))
And I succesfully build my variable name like this:
paste('l$', 'V1_1', sep='')
Why can't I just run a mean call with the pasted variable name?

qplot in ggplot2 not working any longer - (what did I do?)
This is the first time that I have tried to update packages with a
tinkered around with .Rprofile. I start R with R --vanilla and it
does not load my .Rprofile, but when I issue the command
update.packages() R downloads the packages as expected, but then seems
to load .Rprofile before compiling the packages sources. What am I
doing wrong?
kindest regards,

Thougt I understood factors but??
Hi,
consider the following
> a<-gl(3,3,9)
> a
[1] 1 1 1 2 2 2 3 3 3
Levels: 1 2 3
> levels(a)<-3:1
> a
[1] 3 3 3 2 2 2 1 1 1
Levels: 3 2 1
> a<-gl(3,3,9)
> factor(a,levels=3:1)
[1] 1 1 1 2 2 2 3 3 3
Levels: 3 2 1
It is probably something obvious I missed, but reading the documentation
of factor, and levels I would have thought
that both should produce the same output as

regex question on escaping "." (and a couple other regex questions as well)
I have an example where escaping "." does not seem to be behaving
consistently, but perhaps it is due to my misunderstanding. Could someone
explain to me why the below produces the output it does?
It seems to me that in the second example, where I am being more precise
about specifying that a "." (dot) should be between the numbers, should
produce the same output as the first

results of pnorm as either NaN or Inf
I stumbled across this and I am wondering if this is unexpected behavior
or if I am missing something.

Math characters in column heading using latex() in Hmisc
Hi Everybody
I want to print a latex table containing math characters in the column
heading
These are the formulae I want to use as column headings. It prints OK from
TeX

$\bar{C}_{P,y}$
My plan was to create a character vector with these and later rbind the
values to them. When I create the vector like:

Looks like a bug in subsetting of a complicated object
I don't understand what is happening! I have a (large) object sim1, an
matrix list
with dim c(101,101) where each element is an 3*3 matrix. I am
subsetting that with
a matrix coo, of dim c(100,2), of unique indices, but the resulting object
has length 99, not 100 as expected.
Code reproducing the problem follows:

duplicated() and unique() problems
Hi everybody
I have found something (for me at least) strange with duplicated(). I will
first provide a replicable example of a certain kind of behaviour that I
find odd and then give a sample of unexpected results from my own data. I
hope someone can help me understand this.
Consider the following
# this works as expected
ex=sample(1:20, replace=TRUE)

duplicated(ex)
ex=sort(ex)
