Word boundaries and gregexpr in R 2.2.1
Hi
I have a question concerning how to match word boundaries which I bet has a very simple answer, but I haven't found it with trial and error nor by searching the help archives for the terms in the subject line. The problem is this: I have a vector of two character strings.
text<-c("This is a first example sentence.", "And this is a second example sentence.")

gregexpr in R 2.3.0 != gregexpr in R 2.4.0
Hi all
I have a question regarding differences in the way gregpexr works in R 2.3.0 and R 2.4.0.
In R 2.3.0, this is what happens:
> gregexpr(" [a-z] [a-z] ", " a b c d e f ", perl=T)
[[1]]
[1] 1 3 5 7 9
attr(,"match.length")
[1] 5 5 5 5 5
... while in R 2.4.0, this is what happens:

pvclust crashing R on Ubuntu 10.10
Hi all
I am writing to you with a question regarding the pvclust package. And
yes, before the usual people produce their usual
contact-the-package-maintainers line, ye, I tried that but the emails
one can find on the web either bounce or are not responded to. Also,
yes, this error has already been reported as a bug but been shot down
as not reproducible

Hi,
I am a new user of R using R 2.8.1 in windows 2003. I have a csv file with
single column which contain the 30,000 students names. There were typo
errors while entering this student names. The actual list of names is <

I am interested in grouping/cluster these names as those which are
similar letter to letter. Are there any

I have some very long strings and would like to break up each long string

I tried a couple of commands but was not successful. Any help will be

Intercept in lm and in library(car): Anova
Hi
I have two questions regarding the meaning of intercept outputs of lm.
Question 1: In data set 1 (a fully-balanced design), the line with
(Intercept) contains the overall mean, and the estimates contain the
differences from the overall mean (matching those from model.tables).
But in data set 2, the line with the intercept does not correspond to
the overall mean and the estimates don't

NAs produced by integer overflow, but only some time ...
a) Numeric values may be either integers (signed 32 bit) or double precision (53 bit mantissa).
b) Double precision constants are numeric with no decoration (e.g. 61224). Integer constants have an L (e.g. 61224L).
c) 61224*61224 > 2^31-1 so that answer cannot fit into an integer.
d) Exponentiation is a floating point operation so the result of 61224L^2L is a floating point answer that CAN

Regex: workaround for variable length negative lookbehind
Hi all
I have the following regular expression problem: I want to find
complete elements of a vector that end in a repeated character but
where the repetition doesn't make up the whole word. That is, for the
vector vec:
vec<-c("aaaa", "baaa", "bbaa", "bbba", "baamm", "aa")
I would like to get

Hierarchical multi-level model with lmer: why are the highest-level random adjustments 0?
Hi all
I have a hopefully not too stupid question about multi-level /
mixed-effects modeling. I was trying to test a strategy from Crawley's
2013 R Book on a data set with the following structure:
- dependent variable: CONSTRUCTION (a factor with 2 levels)
- independent fixed effect: LENGTH (an integer in the interval [1, 61])
- random effects with the following hierarchical structure: MODE
