Recombining Mon and Year values
R Help
I have a data.frame where I've broken out the year <dbl> and an ordered
month <ord> values. But I need to recombine them so I can graph mon-year in
order but when I recombine I lose the month order and the results are
plotted alphabetical.

Error in lmer: asMethod(object) : matrix is not symmetric [1, 2]
Dear R Users,
I am having trouble with lmer. I am looking at recombinant versus non
recombinant individuals. In the response variable recombinant
individuals are coded as 1's and non-recombinant as 0's. I built a model
with 2 fixed factors and 1 random effect. Sex (males/females) is the
first fixed effect and sexual genotype (XY, YY, WX and WY) the second
one. Sexual Genotype is

data management (subsetting and recombining)
This is an example of two months of data from a twenty four month data set
that I would like to apply this too. These data are subsets of the same
stations throught time, but differing ones were included on different
sampling dates. I would like to subset these data and then put them
together as a big matrix with the by column being RiverMile. What is the
easiest way to proceed as this is a

...you need to modify the IR? Wouldn't the target level lowering
happen later?
How are you actually determining to offload? Is this tied to
directives or using heuristics+some set of restrictions?
Lastly, are you handling 2 targets in the same module or end up
emitting 2 modules and dealing with recombining things later..

What's not possible? I agree some of our local patches and design may

Recursive function calls
My apologies, I know that this is not a new problem, but I'm not sure how
to find the answer
I want to recursively loop over an object and trim trailing white space.
When I use this function on a list of data.frame I get output like this:

stop on rows where !is.na(mydata$ti_all)
Dear R experts,
I got help to build a loop but there is a bug inside it that causes
one part of the mechanism to fail.
It should grow once, but if keep growing on rows where $ti_all is not NA.
Here is a wall of code that very crudely demonstrates the problem,
there is a couple of dim() outputs at the end where you can see how it
the second time around keeps adds (2) rows, but this does not

different output for opt/non-opt on win32 platform
...this... so how many frames/packets of preroll are
required to ensure "perfect" (where perfect = as it would have been
reproduced at this point had the file played from the beginning) output ?
ie basically what i'm asking is what impact does this have on seeking or
editing/cutting/recombining ? Because when you just seek to some random
point... obviously it doesn't have the same memory state as if it had played
to there. I assume the difference is either very small or over such a short
duration that the audio change at a seek essentially masks it ?

rbinding dataframes
I've got a data frame which I've split by a factor,
creating a list of dataframes which I have then done
various operations on individually. I next want to
recombine the resulting dataframes (still held in a list,
still with the same number of columns with the same names)
and there does not appear to be a `good' way to do this -
at the moment, I'm using a for-loop with the rbind

[LLVMdev] Obfuscation Transformations Clobbered by Unkown Optimizations
Hello all,
I am implementing some simple obfuscation transformations in LLVM. One
of the obfuscations involves searching for particular constants, and
"unrolling" them throughout a procedure using arithmetic. In effect,
certain constants are broken up into smaller constants and recombined
as needed using the appropriate operators. I perform this on
intermediate LLVM instructions.

Data Restructuring Question
...ion in order to be able to restructure the first data set to have a similar look as the second, i.e.
VariableName, Run, Location,
temp, 15.0, There # Really Run1
temp, 16.0, There # Really Run2
temp, 17.0, There # Really Run3
Right now I am manually recombining:
tmp_1<-data.frame(data$VariableName, data$ Run1, data$Location)
tmp_2<-data.frame(data$VariableName, data$ Run2, data$Location)
tmp_3<-data.frame(data$VariableName, data$ Run3, data$Location)

Off-topic tcpdump/samba
Hello all
I've been doing some TCP dumps of Samba among other things, to try to
fish out a slight communications glitch that I suspect has to do with a
bad IP stack on an older machine, and I'm wondering if any of you could
help make my life a bit easier:
When doing the dump, I used the '-C' flag which causes capture files to
be rotated when they reach a certain size. I made the

[LLVMdev] Obfuscation Transformations Clobbered by Unkown Optimizations
Matt,
The LLVMCore library provides constant folding automatically. So, when
your obfuscated module is read in and the assembler re-creates your
constants, the arithmetic is done automatically and the constants are
folded. To see where this is done, see lib/VMCore/ConstantFold.cpp

Monitor() - splitting long calls into several sound files
Hi,
I'm not sure whether this is possible but if it is, I'm sure someone on
here might know ...
Is it possible to use Monitor() to record a conversation[1], but make it
start a new pair of wav files at intervals (eg every 15 minutes) if the
calls go on for a long time?
We already have this happening if the callers press a specific key
sequence (which we've defined in features.conf)

Invalid number for the given node in SelectionDAG
I'm trying to replace SDIvRem (whch returns two i16 types) with a custom
that returns i32 or i16. I am getting the Assertion (!Node || ResNo <

Seems that it doesn't like returning one value but how do you return more
than one value?

conditional subset and reorder dataframe rows
Hi List
I have a dataframe (~1,200,000 rows deep) and I'd like to conditionally reorder groups of rows in this dataframe.
I would like to reorder any rows where the Chr.Strand column contains a '-' but reorder within subsets delineated by the Probe.Set.Name column.

negStrandGene <- data.frame(Probe.Set.Name =
