odd behaviour of identical
given what ?identical says, i find the following odd:
x = 1:10
y = 1:10
all.equal(x,y)
[1] TRUE
identical(x,y)
[1] TRUE
y[11] = 11
y = y[1:10]
all.equal(x,y)
[1] TRUE
identical(x,y)
[1] FALSE
y
[1] 1 2 3 4 5 6 7 8 9 10
length(y)
[1] 10
looks like a bug.

New Stack
Hi Experts, I am newbie in R. Could you please share your idea to create a stack with no value or zero value? Nrow=1,Ncol=1, Ncell=1, I aim to work with looping, I want to make a first layer with zero values to add other layers further. Thanks.

help text for which.min
Dear R developers,
I find the which.min function very handy. However, maybe you could
consider a tiny addition to the example data in the the help text.
By adding another zero to the vector x...
x <- c(1:4, 0, 0:5,11)
...the example would more explicitly show that which.min actually
'giv[es] the index of the /first/ minimum or maximum respectively of x'.

Number of CPU's
Any way to get access to the number of CPU's, optionally their type,
from within R? In linux I can just read /proc/cpuinfo but for
win/mac ?
Thanks!

predict lmer
Hi,
I am using lmer to analyze habitat selection in wolverines using the
following model:
(me.fit.of <-
lmer(USED~1+STEP+ALT+ALT2+relM+relM:ALT+(1|ID)+(1|ID:TRKPT2),data=vdata,
control=list(usePQL=TRUE),family=poisson,method="Laplace"))
Here, the habitat selection is calaculated using a so-called discrete
choice model where each used location has a certain number of
alternatives

weighted kernel density estimate
Dear R-users,
I intend to do a spatial analysis on the genetic structuring within a
population. For this I had thought to prepare a kernel density estimate
map showing the spatial distribution of individuals, while incorporating
the genetic distances among individuals. I have a dataset of locations
of N unique individuals (XY-coordinates) and an NxN matrix with the
genetic distances given as a

Extracting selected rows from a matrix to a submatix
I have a matrix M
> dim(M)
[1] 30380 561
I have another list L contains , that contains some row names of matrix M
str (L)
chr [1:21037]
Now I want to extract the submatrix subM (21037 , 561) from the matrix M by matching the rownames (M) to the 21037 rownames o f L
How do I do that ?

Rsync progress indicator?
I've been reading through the man pages for rsync, yet I can't seem to find a way to provide
progress indication and/or current download speed for total and/or individual files...
Can this be done with rsync? Is it an implemented feature.
I thought -v or -vv would do the trick, but it doesn't...
Cheers,

patch for src/main/character.c
Attached is a suggested patch for src/main/character.c. It does not fix
a bug, but rather provides an improvement on the recent extension of
do_grep.
In essence, instead of four occurences of 'invert ^ LOGICAL(ind)[i]'
that accommodate for the option 'invert' added to grep, there is one
occurence of 'LOGICAL(ind)[i] ^= invert' that modifies in-place the
logical vector of

Extract, sum and Loop in R
Hi all,
I have gone through some basics of R in eclipse environment. What I need to
work is more than basic level so I could not find out the solution by
myself. could anyone help me ?
My case,
I have climate data (precipitation) in nc format with single layer for each
time interval in a day. That means for January 1, 2013, I have 8 separate
files each containing 3 hrs cumulative precipitation

arguments imply differing number of rows
4000:6000 gives you 4000, 4001, ..., 6000. I suspect you want
population= c(seq(4000, 6000, length=5), seq(3500, 4300, length=5),
seq(3000, 3200, length=5))

Now, I want to extract all the 104 columns of List1 matching with the 14000 selected rownames from List2.
Psedocode will be something like this:

Use of nesting in lmer- error in numerical expression
Dear R users,
I am trying to fit a GLMM using lmer to a dataset where the brood identity
(LNRREIR) is nested within mothers identity. The reason for this is that
each mother can have several nests within each year and also between years.
I am running the following script (actually I have tried all different
combinations with LNRREIR and mother):

Patch for src/main/character.c, systematizing recent fix to do_grep
The attached patch provides a modification to the recent fix/improvement
to do_grep already included in the most recent development version.
The original fix added new functionality to the grep function by adding
a new parameter, 'invert'. In the source code for the underlying
do_grep, the value of the parameter is used to invert the logical
match-no match flag vector ind. The

Dear all,
I have some csv-files (originating from Excel-files) containing empty

strsplit and the empty string
Hello,
I am wondering about the behaviour of strsplit. When the pattern
matches the beginning of the search string, the mepty string is added to
the result, but that's not the case when the pattern matches the end of
the search string:
strsplit(" hello dolly ")
[1] "" "hello" "dolly"
The man for strsplit explains the algorithm:

SciViews-R_0.8-9 Console problem
Dear R users,
I successfully installed SciViews the other day. However, when I try to
run it now, the command/script window does not appear. Strange. Well,
actually I see a tendency to a script window (in the lower part of the
sciview window where it is suppose to be) during start up, but when the
program is entirely open, the script window is gone.
