bug with strptime, %OS, and "."
Hi R Devel,
I just ran into a corner case with 'strptime'. Recall that the "%OS"
conversion accepts fractional seconds:
> strptime("17_35_14.01234.mp3","%H_%M_%OS.mp3")$sec
[1] 14.01234
Unfortunately for my application it seems to be "greedy", in that it
tries to parse a decimal point which might belong to the rest of the
format:
> strptime("17_35_14.mp3","%H_%M_%OS.mp3")
[1] NA
If I use "_" instead of &q...

Splitting 3D matrix from for loop to generate/save 2D matrices
Hi!
I have a matrix called M with dimension (586,100,100). I would like to split
and save this into 586 matrices with dimension 100 by 100.
I have tried the following for loops but couldn't get it work..
l<-dim(M)[1]
for (i in (1:l)){
save(M[i,,],file = "M_[i].img")
}
Can somebody help me with this? Thanks!

how to convert character string with only month and year into date
...wonder how to convert character time info into date in R.
I searched over the web but did not find answer.
the input character string is something like 03_1993 or 03-1993, so the
precision is at month level. I tried the following but failed.
#R code below.
strptime(c("03_1993"),"%m_%Y")
strptime(c("03-1993"),"%m-%Y")
Can you someone kindly show me to do it?
Many thanks in advance!

identifier and thus undefined behavior). I have seen this cause inscrutable
compilation failures in practice. (With Chandler's approach for initialisms
we may still get leading capitals.)
Trailing _ is better, but still suffers from bugs where the wrong entity is
used:
class A {
bool m_;
A(bool m) : m_(m_) {} // oops, but we diagnose
};
Capitalizing member names has the same problems as capitalizing local
variable names:
struct MyRAIIThing {
Sema &Sema; // =(
};

Just leave off the ".mp3" in your time pattern.

strptime() with format %OS does not print millisecs in MacOS
Hi!
I'm finding this on MacOS Lion 10.7.5

I can solve it with

[1] "2012-02-01 14:13:32.445"

IMO these are pretty feeble objections. The "m_" is silent, for example.

Re : Re : Generate a random bistochastic matrix
Yes, you're right. In fact, it's just an adaptation of a matlab command and the author advises using N^4 replications that's why it's the default in the function. The bistochastic matrix is not my subject of interest, but I need it to perform some random tranformation of a vector of incomes.

functions
I wrote some functions for multiway CANDECOMP, i.e. for least
squares fitting of
a_{i_1\cdots i_m}\approx\sum_{s=1}^p x^1_{i_1s}x^1_{i_1s}\cdots
x^m_{i_ms}
with arrays of arbitrary dimension. Reminded me of the good old APL
days. I could not find this in the archives, but if it's already there,
I would appreciate if someone let me know.

How unzip all files?
Hi
I'm starting to use R in windows. I need unzip some files. Each of them are
in different folders and subfolders. Names of folders have the same
beginning of the name. [example:( ~ / M_ /P_ (...)/ (...)R(...)/*.zip)] I do
not know the expression (character) necessary to call this direction and to
unzip files are in each subfolder.
Thank you.

Variable names rule
If we're talking about member variables, just put an m in front of it,
problem solved. You already have one for s_, and I didn't see you mention
it but I assume you'd want g_ for globals, so m_ makes perfect sense for
member variables and there's no question about UB at that point.

HOWTO Create a PDF Writer in samba
Hi all,
Thought I'd post this to the list as I found a better way of doing
it. Nice to have for posterity.
Please include it in the source of samba if you wish - I hereby license
it under GPL
1. install ghostscript (most distributions include it anyway)
2. put the following in the file /usr/sbin/pdfprint and make it executable
by whatever your guest user for samba is :
