I always use apsrtable in the apsrtable package, which allows you to
specify a vcov matrix using the "se" option. The only trick is that
you have to append it to your model object, something like this:
fit=lm(y ~ x)
fit$se=vcovHC(fit)

Hi,
Does anyone know how to integrate texmakerx and sweave on Windows? I
mean, to run .rnw files directly from texmakerx and get a pdf or dvi file.
Thank you in advance,

Can you please quote what you are referring to?
The subject seems to refer to an R version R-1.7.0 which is for almost a
decade outdated.

Hi All,
As you may know I am trying connect R with java by RJava, now I run the
examples, I got this error
rShowMessage "Fatal error: unable to open the base package
I am using 64bits windows 7 and eclipse. Any suggestions?
Many thanks

Hi,
I've been modelling some data over the past few days, of my work,
repeatedly challenging microbes to a certain concentration of cleaner,
until the required concentration to inhibit or kill them increaces, at
which point they are challenged to a slightly higher concentration each
day. I'm

Hello all. Why doesn't this work?
d=data.frame(y=rpois(10,1),x=rnorm(10),z=rnorm(10),grp=rep(c('a','b'),each=5))
library(lme4)
model=lmer(y~x+z+(1|grp),family=poisson,data=d)
update(model,~.-z)###works, removes z
var='z'
update(model,~.-get(var))##doesn't remove z
update(model,~. -get(var,pos=d))
Note that that isn't exactly what I recommended. If you look at the
example in the help page for combine(), you'll see that it is combining
RF objects trained on the same data; i.e., instead of having one RF with
500 trees, you can combine five RFs trained on the same data with 100
trees each into

I thank you all for the insightful answers. I'm quite a rookie in R and have
built a code that didn't take data frames into account. But I suppose I'm
now convinced that they're actually a practical structure for organizing the
data... so I'll adhere to the Data Frame Club soon enough.
Best regard
Dear R-users,
Let's consider the following snippet:
f <- function(x) tryCatch(sum(x),error=function(e) stop(e))
f('a')
As expected, the last call returns an error message: Error in sum(x) :
invalid 'type' (character) of argument
My questions are the following:
1- can I easily ask the stop f
Thanks very much Luke for clarifying.

for example:

Could it be that you are running on a 32-bit version of R? 536870912
* 4 = 2GB if those were integers which would use up all of memory.
You never did show what your error message was or what system you were
using.

It was gently suggested to me in a private message that to achieve
*complete* control over the inputs and outputs in R graphics one should be
using grid graphics. I concur with that suggestion and wish to amend my
previous statement accordingly.
With kindest thanks,
