Perl question
I'm working on the installer code, but I don't know Perl well enough.
What is a good Perl equivalent of the R statement
if ( s %in% c('string1', 'string2', 'string3') ) ...
I can do it with
if (s == "string1" || s == "string2" || s == "string3") ...
but I've got a feeling there's a better way to do it using associative

Colors in mtext
I want to assign different colors to different strings using
mtext(...). However, when I use something like

col=c("black","blue","red"), side=3, line=0)
string2 and string3 are printed over string1. When I use

Indexing a vector by a list of vectors
Hello R-help -
I have
vec <- c("string1", "string2", "string3")
ind <- list(c(1,2),c(1,2,3))
I want "vec" indexed by each vector in the list "ind".
The first element of the list I want would be vec[c(1,2)],
the second element would be vec[c(1,2,3)], like the following.
[[1]]
[1] "string1" "string2"
[[2]]

fuzzy search
This may be offtopic to Rails, but what are people doing to find records
based on fuzzy string matches? For example, if you wanted to find a
Person with name "David Heinemeier Hansson" but searched using the
string "Dave Hansson".
Currently I am find_by_sql that calls the PostgreSQL function
"levenshtein(string1, string2)" which returns results with a score

AD integration not working after move/version
Hi!
I am in a bit of trouble, I have moved a samba installation from one virtual host to another keeping the configuration files and filesystems. But during the transition something broke, now windows users are no longer able to access their shares. I think it has to do with the AD integration.

Database usage technique -- user-specified fields
Hello folks-
In one particular app, it would be useful for the customers to be able
to specify the significance (and presence) of fields. For example,
consider a CONTACTs database. User 1 wants to have phone1, phone2,
phone3, and User 2 wants to have 4 address fields.
Generically, this could be done by having a CONTACT with, say, 10
strings, 10 integers, etc. The user''s account

case conversion and/or string comparison
This is no doubt trivial but after searching the help files and the web, I
cannot seem to find it.
1) How do I convert 'hgt' into 'HGT' in R?
2) How should I have used the help facilities to find this?
At the end of the day, all I want to do is case insensitive string
matching... i.e. 'if ("HGT" == 'hgt') print('this should be true')'

strtoi output of empty string inconsistent across platforms
Identified as root cause of a bug in data.table:

On my machine, strtoi("", base = 2L) produces NA_integer_ (which seems
consistent with ?strtoi: "Values which cannot be interpreted as integers or
would overflow are returned as NA_integer_").
But on all the other machines I've seen, 0L is returned. This seems to be

that produced a timestamp in 4 columns: Year, Day of Year, Time in (H)HMM
and Seconds. I would like to have R interpret these columns as a time
