getting the by() function to work properly
Hola everyone,
Solving this issue would be a huge time saver for analyzing my thesis data, so I'll try to be as concise as possible and hope that someone can give me a hand.
I am trying to run a function that I created, which works fine until I try to use it with the by function. That function is listed at the bottom (f3) just in case that might be the issue. Essentially I have compiled a

Fwd: How to get all combinations between two character vectors?
Hi Rainer
Or maybe you are referring to the outer function.
I'm a newbie in R, but I recently read something about it in the pdf book named below (pages 91-2). I send to you an excerpt:

Vectorization of math function failed?
Hi,
After reading https://llvm.org/docs/Vectorizers.html#vectorization-of-function-calls
I decided to write the following C++ program:
#include <cmath>
using v4f32 = float __attribute__((__vector_size__(16)));
v4f32 fct1(v4f32 x)
{
v4f32 y;
y[0] = std::sin(x[0]);
y[1] = std::sin(x[1]);
y[2] = std::sin(x[2]);
y[3] = std::sin(x[3]);
return y;
}
v4f32 fct2(v4f32 x)

summary.table bug in parameter (and fix) (PR#2526)
I sent this in with an old version, but it's in latest version as well. The fix is simple.
In the summary.table function, the parameter is calculated incorrectly
for a test of independence among all cells when the table is more than
2-way table.
Example:
Consider X:
> X
a b c
1 A1 B2 C1
2 A3 BA3 C2
3 A2 B1 C4
4 A1 B2 C3
5 A3 BA3 C2

restricted coefficient and factor for linear regression.
Hi,
my data set is data.frame(id, yr, y, l, e, k).
I would like to estimate Lee and Schmidts (1993, OUP) model in R.

** procedures for creating dummy variables are omitted **
** di# and dt# are dummy variables for industry and time **

stripplot, lattice
hello,
i can't figure out how to set position of panels of my stripplot -
i`d like the panels of one level of the factor stage (nr. of panels within
each stage, A: 12, B: 12, C: 12, D: 4, each panel representing a site) to be
in one column, with A to D from left to right and with descending site.nr at
each row.
like:
A1 B1 C1 D1
A2 B2 .. ..
A3 .. ..
..
how is this achieved?
any help

[LLVMdev] [Polly] GSoC Proposal: Reducing LLVM-Polly Compiling overhead
Dear Tobias and all LLVM/Polly developers,
Thank you very much for all your help and advice.
I have submitted my proposal to GSoC 2013 application system:
http://www.google-melange.com/gsoc/proposal/review/google/gsoc2013/star/1.
Some tables and paragraphs are simplified to make it more readable on GSoC official pages. Any suggestion or comment would be appreciated.

I'm very sorry for my repeated question, which i asked 2 weeks ago, namely:

how to cat / grep from dbox files
Dear List members
I am new to dovecot and am looking for a solution. I have googled as
much as I could, but most likely my search criteria was wrong, and hence
asking here.
I am familiar with maildir format, and could easily do cat / grep / sed
on those files to extract data. The server I am looking at now uses dbox
format, which seems to store data in a different way. just to give you
