Slow computation in for loop
Dear members,
I'm using R to do some test computation on a set of parameters of a
function. This function is included in three for() loops, first one for
replications, and the remaining two cycling through possible parameters
values, like this :
for (k in replicates) {
data <- sampling from a population
for (i in param1) {
for (j in param2) {
result <- function(i,

vector of center of
Hello
I have a vector gd of 279 values of diameter of limpets.
Using 'hist(gd, breaks=seq(10,60,5),plot=F)' I can obtain a vector of
10 centers of size-class ($mids).
But I'd like to work on a vector of 279 values being the mids (centers
of size-classes) corresponding to the respective 279 values in gd.
I looked in the different manuals and in archives of list but didn't find

simple test on slope of lm()
Hello
I want to compare the slope (let's say 'b') of a linear model obtained
with lm() to a theoretical value (let's say 'th').
To do so, I think I should compute a 't value' using
something like :
(b - 'th')/standard.deviation(b)
and then look at the p-value of this computed t.
I don't understand how to do this in a simple way, just using lm()

Matching colors with lattice auto.key
Hello !
I try to plot some data with lattice function xyplot. These data are
separated in two groups by a factor. If I let the default color and symbol

and pch arguments, the plot is right but the legend still reflects default
settings. Isn't the auto-key feature normally taking its arguments from the

Re: R-help Digest, Vol 2, Issue 26
With the same system configuration (WinNT4 SP6 and 1.7.0), I get such a Dr
Watson crash each time I try to use the Change dir... command in the File
menu of Rgui.exe. I doesn't seems to happen if I do this immediately after
starting R but well if I already did some computation.
I don't have any problem by using directly setwd().
