No subject
Dear R Gang:
I have a Macintosh G4 powerbook, running OS 9.2. Last week I
ran a statistical analysis program that I wrote in R for two days
continuously. The program does repeated intensive computations on a
large data set.
The program completed its task successfully, but during the
process I noted that the computer seemed to be running unusually hot.
Shortly after the program stopped,

How to access values returned by R functions (to put into vectors)?
The question is general for all functions, but here is a specific example -
# For the logistic regression of the following correlated variables:
C <- c(457, 1371, 4113, 12339, 37017, 111051, 333153, 999459)
E <- c(0.003858377, 0.014334578, 0.014092836, 0.737950754, 0.996371828,
0.997482379, 1.005569257, 0.994382856)
# The nls function:
A = nls(E~(Em*C^p)/(C50^p + C^p),
Assigning NULL to large variables is much faster than rm() - any reason why I should still use rm()?

Assigning NULL to large variables is much faster than rm() - any reason why I should still use rm()?
Hi,
in my packages/functions/code I tend to remove large temporary
variables as soon as possible, e.g. large intermediate vectors used in
iterations. I sometimes also have the habit of doing this to make it
explicit in the source code when a temporary object is no longer
needed. However, I did notice that this can add a noticeable overhead
when the rest of the iteration step does not take that

Problem merging two data frames
Hello everyone,
Merging two dataframes should be easy. However when I try to merge, R
doesn't recognize identical values, even if I am doing it by values that
have no decimals.

Creating a table
Dear R List,
I am a new to R, so my question may be easy to answer for you:
I have a dataframe, for example:
df<-data.frame(loc=c("A","B","A","A","A"),
year=as.numeric(c("1970","1970","1970","1976","1980")))
and I want to create the following table without using loops:

tip: large plots
Hi all,
I'm working with a bunch of large graphs, and stumbled across
something useful. Probably many of you know this, but I didn't and so
others might benefit.
Using pch="." speeds up plotting considerably over using symbols.
> x <- runif(1000000)
> y <- runif(1000000)
> system.time(plot(x, y, pch="."))

Linear Mixed Effects
Hi,
I have implemented the lme in SAS and specified the random effects
covariance structure as unstructured using the statement "random / type=UN"
I want to specify same in R but not able to know how to do it.
Can anyone please advise me on how to proceed.
Thanks

How to get around heteroscedasticity with non-linear leas t squares in R?
Your understanding isn't similar to mine. Mine says robust/resistant
methods are for data with heavy tails, not heteroscedasticity. The common
ways to approach heteroscedasticity are transformation and weighting. The
first is easy and usually quite effective for dose-response data. The
second is not much harder. Both can be done in R with nls().

Small patch to Effect.Highlight
I sometimes highlight a div that originally has no background colour.
The current Effect.Highlight will leave my div with a white
background, and it was not quite right for my purposes.
My one-line-patch is simply to add the afterFinish option if there is
no current background colour (insert at line 268 of effects.js
rev:1756)
if ( !current ) options.afterFinish = function(effect){

how to divide each column in a matrix by its colSums?
Hi,
I have a matrix, say
m=matrix(c(
983,679,134,
383,416,84,
2892,2625,570
),nrow=3
)
i can find its row/col sum by
rowSums(m)
colSums(m)
How do I divide each row/column by its rowSum/colSums and still return in
the matrix form?
(i.e. the new rowSums/colSums =1)
Thanks.

suppressing stderr output from system() calls
Dear list,
I'm trying to suppress/redirect/squash the output from commands like install.packages, or download.file. The problem is that none of: sink(..., type="message"), sink(..., type="output"), capture.output, suppressMessages are quite doing the trick. Output gets written to the stderr stream, despite any combination of the above suppression commands.
