nlme question
I have a need to call and pass arguments to nlme() from within another
function. I use R version 1.8.
I have found an apparent way to make this work, but I would appreciate
some comments on whether this fix is really appropriate, or there is
another way to do it that does not involve changing the source code. I
don't have enough experience to start changing the sorurce code of a
library

Cross validation, one more time (hopefully the last)
I apologize for posting on this question again, but unfortunately, I don't have and can't get access to MASS for at least three weeks. I have found some code on the web however which implements the prediction error algorithm in cv.glm.

metafor - interpretion of QM in mixed-effects model with factor moderator
Hi,
I'm using metafor to perform a mixed-effects meta-analysis. I'd like to
test whether the effect is different for animals and plants/whether "group"
(animal/plant) influences the effect size, but am having trouble
interpreting the results I get. I've read previous posts about QM in
metafor, but I'm still a bit confused. I've dummy-coded the factors:

xyplot (Lattice): Group order in display
Dear R users,
I would like one of my groups in xyplot to appear to lie 'behind' the other
groups. I have searched for help and find many, many topics about panel
order (e.g., "as.table"), but that is not what I need.
What is odd is that the group that I want to appear 'behind' the others
(PROFILE) is the last in alphabetical order but xyplot is plotting it first.

Types in grouped multi-panel (lattice) xyplot
Apologetic prologue: I've looked through the mailing list for an answer to
this (since I'm sure it's trivial) but I have not been able to find a fix.
So the problem is that I want each group to have a different type of plot.
"Probes" should be points and "Segments" should be lines (preferably using
the segment plot command, but I've just been trying --

NA Replacement by lowest value?
Hi all,
I need to replace missing values in a matrix by 10 % of the lowest available value in the matrix. I've got a function I've used earlier to replace negative values by the lowest value, in a data frame, but I'm not sure how to modify it...
nonNeg = as.data.frame(apply(orig.df, 2, function(col) # Change negative values to a small value, close to zero

logistic model cross validation resolved
This post is NOT a question, but an answer. For readers please disregard all earlier posts by myself about this question.
I'm posting for two reasons. First to say thanks, especially to Dimitris, for suggesting the use of errorest in the ipred library. Second, so that the solution to this problem is in the archives in case it gets asked again.

How to control spaces between axis, tick and label in xyplot or xYplot?
Dear R users,
I encounter a problem regarding space control in xyplot. Basically, I want
to control spaces between label, tick and axis. I remember there is a
function called mgp in general plot. Is there a similar function for xyplot
or xYplot?
Below is my basic code:

What is the equivalent function in R to xyplot in S?
Page 140 of MASS uses the function xyplot. But I don't find it in R.
Is there a package that I should load to use xyplot. Or there is a
function with a different name in R that does the same thing as xyplot
in S.
xyplot(Gas ~ Temp | Insul, whiteside, panel =
function(x, y, ...) {
panel.xyplot(x, y, ...)
panel.lmline(x, y, ...)
}, xlab = "Average external temperature (deg. C)",

Adding reference lines to xyplot
I'm trying to add a set of reference lines to a multipanel xyplot
xyplot(y ~ x | Visit,
panel = function(x, y, ...){
panel.xyplot(x, y, ...)
abline(v = c(0.5, 1))
})
However, the reference lines are different for different visits. For
example, for the first 2 visits, I'd like vertical lines at x = 0.5 and 1.
For visits 3 and four, I'd like vertical lines at x = 1 and 1.5. I can

highlighting subset of point with xyplot (or Hmisc(xYplot))
Hello all,
I am trying to use xyplot to give a six panel plot and to highlight
only points (in any panel) that meet a certain criterion. With the
plot command I would do something like:
plot.default(filein$Site,filein$circ.conc)
points(filein$Site,filein$circ.conc,type="p",
pch=ifelse(filein$p.value<5e-02,19,21))
I had thought I could just stick in the pch line from above into

Labeling points with xYplot
Hello R-Users,
I am trying to label points on an xYplot. I can label the points, but
then I lose the error bars. I suspect that I should be using
panel.xYplot rather than panel.xyplot, but that didn't work either...
Can anybody help me out? Example code is below. First xYplot has error
bars, second tries to label the points and the bars disappear.
Thanks,

I have a question regarding xyplot. I managed to make a xyplot of all the
IDs by using the syntax below:

Now, I'd like to make a graph of a specific ID number (e.g., only ID number

Could anyone let me know how I can make a graph of a
