Spaces in a name
I am reading regressors from an excel file (I have no control over the file)
and some of the element names have spaces:
i.e. "Small Bank Aquired"
but I have found that lm(SourceData ~ . - "Small Bank Aquired", mcReg)
doesn't work (mcReg = modelCurrentRegressors)
As they are toggles I have ran them through factor() to be treated propertly
as 0 or 1 but due to the fact I

Vunerable shell scripts
I made a list of /usr/bin scripts which allows /tmp races. Following
ones creates /tmp/something.$$, then, with no

Feed rle() output to hist()
I want to make a histogram from the lengths vector which is part of the
output of rle. But I don't know how to access that vector so that I use it
as an argument of hist(). What argument must I use so that I use the
lengths vector as an input to hist()?
Example output is:
Run Length Encoding
lengths: int [1:4] 1 2 3 3
values : num [1:4] -1 1 -1 1

formatting a list
Hi,
I am new to R and need to read in a file with 19 columns and 7000 rows
and make it into a list of 7000 lists with 19 items each. For a
simpler case of 10 by 10 table I used x <-scan("file",
list(0,0,0,0,0,0,0,0,0,0)), perhaps clumsy, but it did the job.
However with the large 19x7000 (which needs to be transposed) I am not
sure how to go about it.
Coudl somebody suggest a way?

Yet another data structure + pack/unpack question (win32-service)
Hi all,
If you take a look at the service.rb file in the win32-service
repository (the new one in the toplevel repository path), I''ve got this
bit of code, which succeeds, but I can''t seem to unpack the data
structure properly. Did I pack it wrong to begin with? I should know
this but I''m spacing out.

[LLVMdev] Can simplifycfg kill llvm.lifetime intrinsics?
This looks like a bug in simplifycfg. We should preserve lifetime
intrinsics due to the reasons I described.
The code in //lib/Transforms/Utils/Local.cpp:
if (Succ->getSinglePredecessor()) {
// BB is the only predecessor of Succ, so Succ will end up with exactly
// the same predecessors BB had.
// Copy over any phi, debug or lifetime instruction.

[LLVMdev] Can simplifycfg kill llvm.lifetime intrinsics?
Hi!
I'm working on ASan option that uses llvm.lifetime intrinsics to detect
use-after-scope bugs. In short, the idea is to
insert calls into ASan runtime that would mark the memory as "addressable"
or "unaddressable".
I see the following problem with the following "trivial" basic block:

Problems with lpSolve/Memory ? R crashes
Hello!
I have a curious problem, which I cannot solve.
With my code I solve thousands of small linear programs with the package lpSolve automatically.
But R crashes sometimes (~always, but always on different linear programs) in a strange way.
For illustration, I tried to prepare a simple example, which shows the nature of the problem.
The function aaa (see below) declares some constants (only in

Robust regression error: Too many singular resamples
Hello.
I've got a dataset that may have outliers in both x and y. While I am not
at all familiar with robust regression, it looked like the function lmrob in
package robustbase should handle this situation. When I try to use it, I
get:
Too many singular resamples

Looking into it further, it appears that for an indicator variable in one of
my interaction terms, 98%

Undef/poison semantics
Hi,
I'm new to the LLVM mailing list, but I've been working on tools for symbolic execution/formal modeling of LLVM off and on for a while.
I’m trying to understand the current status of the LLVM undef/poison semantics from a frontend/verification perspective. I saw there was a lot of interest in a proposed semantics in late 2016 and mid-2017. Perhaps this was due to the “Taming

R package: autocorrelation in gamm
Dear users
I am fitting a Generalized Additive Mixed Models (gamm) model to
establish possible relationship between explanatory variables (water

In the case of the inner waters, I have applied satisfactoryly (by

guestmount fails after linux kernel update 01/10/2018
Hello,
I had been using guestmount to mount a raw image and it has been working
great until I updated the kernel on 01/10/2018. I am running ubuntu 16.04
LTS, and have changed the read permissions to the vmlinuz as I have done
with previous kernels. The only change to my system between working and not
working is the kernel update from this morning. I am concerned this might
be related to the

Kernel panic with virt-builder etc.
Hi there,
I am trying to write an article on virt-builder and managed to compile
version 1.24.1 of libguestfs on Ubuntu 13.10 (I had mixed success with
the git version and 1.25.x). When I am running virt-builder I am getting
an error message:
virt-builder: error: virt-resize failed
Upon further investigation it turns out that there's a kernel panic when
booting the freshly created image.
