String manipulation
Please consider following string:
MyString <- "ABCFR34564IJVEOJC3434"
Here you see that, there are 4 groups in above string. 1st and 3rd groups
are for english letters and 2nd and 4th for numeric. Given a string, how can
I separate out those 4 groups?
Thanks for your time

getting all pairwise combinations of elements in a character string
I'm able to do this as follows, but am wondering if anyone knows a
simpler way which still avoids explicit loops?
> (mystring <- letters[1:5])
[1] "a" "b" "c" "d" "e"
> unlist(sapply(mystring[-length(mystring)],
+ function(x)
paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep="")))

Weird behaviour of tab characters in a string in R (vs Python)
Hello,
I wanted to parse some information from a text, where fields are tab
separated.
When I copy the text into an R session (under emacs) like:
mystring <- "field1 field2 field3"
the tab character is replaced by a single space!
For ex, if I type mystring, I get:
"field1 field2 field3"
The tabs have disappeared!!!
I checked with Python that the text I copied was tab

[LLVMdev] Problem in llvm gcc back-end
HI,
While I testing some code, I found some problem on Union handling.
I've wrte following test code, and it has union assignment.
The code's output is
from pointerToUnion: chars mystring, length 64
from original: chars mystring, length 8000
It's caused by second char member(charlength) of LongestMember.
For union assignment, llvm-backend seems generates assigning each
member of

How to test views with Nested Resources and Partials
Hi everyone,
I am relatively new to rspec and I am running into a wall in testing my
views. I have a RESTful resource Contracts with a nested resource of
Line_items.
I am trying to figure out how to test the "edit" form of the Line_items.
What complicates this is the nested routing and how to account for it,
and that there is a partial form (_form.haml) that both the edit.haml

#create tests fail when I add FriendlyId to my model
I am doing controller testing, and I can''t seem to get the create

it out of the model, the tests all pass perfectly. The moment I add it

Bug: time complexity of substring is quadratic as string size and number of substrings increases
Hi all, (and especially hi to Tomas Kalibera who accepted my patch sent
yesterday)
I believe that I have found another bug, this time in the substring
function. The use case that I am concerned with is when there is a single
(character scalar) text/subject, and many substrings to extract. For example
substring("AAAA", 1:4, 1:4)
or more generally,
N=1000

Retrieving the context
Dear list,
I have a general problem that I really don't know how to solve efficiently
in R. Lets say we have a sequence of things, like for instance a string of
words, that is stored in a file. We need all the words in a table format, so
therefore we create an id for the word, that links the word to a file and
the position of the word within the file, like:
#In this case a very short file

Help with replacing a substring in a string
Dear R Users,
I am trying to replace a substring in a string with something else.
For example:

"abc degg hijk"
I have tried the replace.substring.wild function in the Hmisc package but get this error:

[LLVMdev] Should the function operand flag 'sret' match the flag in function declaration?
I have these two instructions, first one inside some procedure, second
one is an outside declaration.
Code verification passes and it runs, but incorrectly.
Every time I saw such situation coming from c++ compiler, attributes
'noalias sret' appear on both call and declaration.
Does such situation make sense, or (as I guess it is) a bug in verifier?
I think verifier should match at

RW 0.64.2 substring() string truncation?
Hi,
(First, apology for my earlier incorrectly addressed "subscribe"
post.)
Can somebody tell me what exactly is going on below. Basically, I am
running into some kind of "string truncation" problem when I try
to get a substring starting past the 8192nd character (see sample
session below). There doesn't appear to be any problem creating the

scope, lme, ns, nlme, splines
I want to fit a series of lme() regression models that differ only in the
degrees of freedom of a ns() spline. I want to use a wrapper function to do
this. The models will be of the form
y ~ ns(x, df=splineDF)
where splineDF is passed as an argument to a wrapper function.
This works fine if the regression function is lm(). But with lme(),
I get an error. fitfunction() below demonstrates this.
