Dropping rows conditionally
Dear R-help team,
I am getting addicted to using R but keep on getting many challenges on the way especially on data management (data cleaning).
I have been wanting to drop all the rows if there values are `NA' or have specific values like 1 or 2 or 3.
mdat <- matrix(1:21, nrow = 7, ncol=3, byrow=TRUE,
dimnames = list(c("row1",

update matrix with subset of it where only row names match
I guess this has a simple solution:
I have matrix 'mat1' which has row and column names, e.g.:
A B C
row1 0 0 0
row2 0 0 0
....
rown 0 0 0
I have a another matrix 'mat2', essentially a subset of 'mat1' where the
rownames are all in 'mat1' e.g.:
B
row3 5
row8 6
row54 7
I want to insert the values of matrix mat2 for column B (in reality it
could be some or

panel ordering in nlme and augPred plots
Dear all
I am trying nlme together with Pinheiro/Bates book. I constructed
grouped data object with suitable plotting layout (according to
some common factor, panels from bottom to top are in increasing
order).
When I do nlme(... some stuff...) I get fitted object which I can plot
with
plot(augPred(fit.nlme6, level=0:1))
but it results in completely different ordering. Is there any way

max and in the zoo package
hi everyone.
i am dealing on a zoo-class object.i am aware of the 'min' and 'max' function to get the minimum and the maximum values.getting these maximum and minimum values is ont thing.but, how to get the (zoo) dates these values occur ?
in fact, in analysing a time series i am interested in the particular (extreme) values AND in the moments they happen.
regards.edouard.

Scriptaculous and Photo Flipper a la TagWorld?
I saw a Flash-based photo-flipper on TagWorld (
http://www.tagworld.com/thepostalservice) and thought it would be nice to do
something similar in Scripaculous. Anyone interested in taking a shot at it?
Since rotation isn''t supported in CSS, what I would imagine would be a
z-ordered "stack" of DIVs, possibly of slightly different sizes or just
x/y-offset a bit from each other.

beryl fork
I've seen that a lot of inaccurate and faulty information about this.
All technical reasons (alternative configuration system, alternative
decorator, xinerama...) for this fork are incorrect and I know that at
least Quinn Storm is aware of this, based on a phone conversation we had
last week.
I've designed compiz to be extremely extensible. The plugin system
should allow people to do

Bug#454678: r-base-core: Crash when calling edit.matrix with edit.row.names = TRUE when there are no rownames (PR#10500)
Ben,
Thanks for the bug report. I am off two minds about it as discussed below.
But as it does indeed create a crash / segfault, I am passing this on to the
R bug tracker. A suggested two-line patch is below; I tested the patch
against a 'vanilla' 2.6.1 source tree.

(PR#10500) Bug#454678: r-base-core: Crash when calling
I would say this was user error (insisting on editing non-existent
rownames), although the argument is documented. You could argue that
there are implicit rownames, but they would be 1, 2 ... not row1, row2
.... And rownames(mat) is NULL.
For an interactive function the best solution seems to be to throw an
error when the user asks for the impossible.
I'll fix it for 2.7.0: it
