?to calculate sth for groups defined between points in one variable (string), / value separating/ spliting variable into groups by i.e. between start, NA, NA, stop1, start2, NA, stop2
Dear useRs,
Thanks for any advices
# I do not know where are the examples how to mark groups
# based on signal occurence in the additional variable: cf. variable c2,
# How to calculate different calculations for groups defined by (split by occurence of c2 characteristic data)

Why does Bootstrap work for one of similar models but not for the other?
Dear all,
Could anyone help me figure out why bootstrap works for one of similar
models but not for the other and how I can solve it?
I am using R 2.11.1 in Windows and would like to get confidence
intervals for my models A and B by bootstrapping. However, bootstrap
gives expected output for the model A but not for B, which I found was
puzzling because the structure of the models is

Transparent Bands in R
Hello All,
My question is regarding the attached plot. I would like to have multiple
transparent green bands running the length (yaxis) of the plot the width of
which is determined by the green lines at y=0 in the plot. Can you suggest a
way to do it?
For those who can't or are unwilling to download the file the plot is at

multiple plots and looping assistance requested (revised codes)
Hi Irucka,
I tried it and was able to plot it without any errors.? Here, your code indicates you need two lines. temper[[i]][1]
?temper[[1]][1] # which is the column 1.

[LLVMdev] Can I get the binary address of a for-loop statement?
Hi, all
What I want to do is to locate the range of a for-loop statement in
a binary. For example, given a for-loop statement belows,
for (stat1; stat2; stat3) {
/* do something */
}
Is it possible to get information about the range (binary address)
of the above for-loop, say, 0x0100 - 0x0120.
One idea comes up in my mind is adding passes to retrieve such
information in LLVM, then use

gee and geepack: different results?
Hi, I downloaded both gee and geepack, and I am trying to understand the
differences between the two libraries.
I used the same data and estimated the same model, with a correlation
structure autoregressive of order 1. Surprisingly for me, I found very
different results. Coefficients are slightly different in value but
sometimes opposite in sign.
Moreover, the estimate of rho (correlation

[PATCH 0/5] Fixes to resize2fs (RHBZ#755729, RHBZ#801640)
https://bugzilla.redhat.com/show_bug.cgi?id=755729
This bug reports that the error message printed by the resize2fs API
calls (which comes directly from the resize2fs command) says:
Please run 'e2fsck -f /dev/vda1' first.
That command is not possible from guestfish (where it would be
'e2fsck-f' or 'e2fsck ... forceall:true').

maxNR - Error in p(a, b) : element 1 is empty; the part of the args list of '*' being evaluated was: (b, t)
Hello everyone...
We were trying to implement the Newton-Raphson method in R, and estimate the
parameters a and b, of a function, F, however we can't seem to implement
this the right way. Hope you can show me the right way to do this. I think
what we want R to do is to read the data from the website and then peform
maxNR on the function, F. Btw the version of R being used is "RGui for

coercing a list into matrix
Dear list,
I have a list of number sequences. Each number sequence has different
numbers of elements. Is there a quick way (other than to iterate
through the entire list) way to coerce list to matrix with NAs filling
in the short sequences?
An example of what I mean is this:
A <- list(c(3,2,3),c(6,5))
I'd like to get A so that it is

6 5 NA

[PATCH v2 0/5] daemon: generate almall the API OCaml interfaces
Hi,
as a followup for the signature fix for mount_vfs [1], here it is a
patch series to generate automatically all the OCaml interfaces of
daemon actions.

Thanks,

First value in a row
Hi.
This is likely a trivial problem but have not found a solution.
Imagine the following dataframe:
Lat Lon x1 x2 x3
01 10 NA NA .1
01 11 NA .2 .3
01 12 .4 .5 .6
I want to generate another column that consist of the first value in
each row from columns x1 to x3. That is
NewColumn
.1
.2

Any input greatly appreciated,
Thanks,

[LLVMdev] Can I get the binary address of a for-loop statement?
In general, this is not possible. Consider, for example, the fact that various optimization passes may reorder the code, including such things as hoisting computations outside of the loop, and enclosing loops, scheduling those instructions before others that did not originate from source lines within the loop, etc. That's not to mention things like loop unrolling.
That said, especially at low

Fishers exact test at < 2.2e-16
In an effort to select the most appropriate number of clusters in a
mixture analysis I am comparing the expected and actual membership of
individuals in various clusters using the Fisher?s exact test. I aim
for the model with the lowest possible p-value, but I frequently get
p-values below 2.2e-16 and therefore does not get exact p-values with
standard Fisher?s exact tests in R.
