Problem with "merge" command duplicating values
Hello,
I am attempting to merge 8 different data sets into a "grand merge" data
set; all their variable names are common except for the the gas measured.
However, when I did a quick stat summary comparison of merged data with
unmerged data, it turned out that R mysteriously duplicated thousands of
values in the merged set and I have no idea why. I've not had this problem
with merge

how to control ticks
Hi,
I want 12 ticks at axis 1 and want to write Jan-Dec on each.
something like:
axis(1, at=1:12, labels=c('J','F','M','A','M','J','J','A','S','O','N','D'))
I could omit default ticks but now how to control ticks.
plot(file$time, file$ch4*1000, ylim=c(1500,1700), xaxt='n', xlab= NA,

kaleidoscope ch4 jit example regression?
https://llvm.org/docs/tutorial/LangImpl04.html has an example where
the function `foo` gets redefined, and the JIT returns evaluation of
the latest definition. I thought my code was wrong, but it seems that
the binary produced by `ninja Kaleidoscope-Ch4` has the same bug.
Granted, my LLVM checkout is from Nov 3 2018 (r346062). Is this a known issue?

kaleidoscope ch4 jit example regression?
Hi Nick,
I was not aware of it, but it makes sense given the recent switch to ORC2, which has different symbol resolution rules.
I am out on vacation this week, but will take a look when I get back and see if I can restore the old behavior.
Cheers,
Lang.

add data from .RData file
I got two .RData file e.g data.2005.RData & data.2006.RData
I would like to combine these two different data set and make single RData
file.
in both file there are some NULL files are also available and I would like
to clear this NULL files also.

difficulties with read.table applied to files from URL
Hello,
I am using read.table to read files directly from a public ftp site. I have
a general list of files that may or may not exist in the ftp directory, but
my hope was that R would read the file if it existed and ignored it if it
didn't exist and move on to the next one. However, when R arrives at a file
that does not exist I get the error message "Error in file(file, "rt") :

Not yet unfortunately. I've had my head down working on a jut-linker

[LLVMdev] Handling ELF groups.
So I was looking into handling ELF groups today in the Atom model. It
appears that we will need to add the concept of a group to the atom
model directly, as modeling it with references fails to capture some
semantics.

Groups in ELF are collections of sections that must be either included
or excluded as a unit. They also are used to

Any LLD guarantees on section alignment across TUs?
Suppose i write
// foo.cpp
__attribute__((section(“foo”))) int x;
// bar.cpp
__attribute__((section(“foo”))) int y;
And i compile and link these two object files together using lld. What
assumptions can I make regarding alignment/padding between the two symbols?
I’m comfortable getting an answer by reading the source, but that won’t
tell if any properties i discover are guaranteed or just

problem replacing NA's in a dataset (10% remain after removal attempt)
Hi all,
I'm attempting to gap-fill a dataset, replacing the missing values with
each month's day or night median value.
The problem is that my code results in some, but not all the NA's being
replaced and I cannot figure out how this is possible. When I look at
the individual line's where the NA's remain, they should have been
captured in my code as far as I can tell.

5.1 surround channel coupling
It obviously would be nice to have such a mode available, for e.g. DVD audio
compression. Apparently, the list doesn''t tell me too much about it. My
questions are:
1. What is the current status of the 5.1 channel coupling in Vorbis?
2. If I''ll be interested in participation in its development, what is the
recommended reading?

Repeatability and lme
Dear R-help list members
I gathered longitudinal data on fish behaviour which I try to analyse using
a multi level model for change. Mostly, I am following Singer & Willett
(2003), who provide also the S/R code for their examples in the book (e.g.
http://www.ats.ucla.edu/stat/Splus/examples/alda/ch4.htm). Of course I am
interested in change over time, but I am also very much interested in

[LLVMdev] SCEV and induction variable identification
Hi Fellows,
The goal is to find the induction variable for a loop, where the
induction variable increments with the multiplication, division or shift
operations, like this one:
sz = 8;
do {
... ...
sz = sz / 2;
} while (sz)
Is SCEV capable of detecting the induction variable 'sz' in this case?
The code snippet I am using to solve the problem is

[LLVMdev] Handling ELF groups.
I support Nick's option too. I think handling groups is another example of
using follow on references.
One question is how does an atom outside the group refer to the main atom
here ? Will not garbage collection cleanup the main atom/signature atom
because there are no references ?
Thanks

Advice on picking a regression method
Dear R-users,
There are tons of methods out there for fitting independant variables to a
dependent variable. All stats books tell you about the assumptions behind
OLS (ordinary least squares) and warn against abusive use of the method
(which many of us do disregard by lack of a better knowledge). Most
introductory text books stop there and don't tell you what the next best
option might be. I
