Help rewriting looping structure?
...gh all records across 5 fields to calculate the cumulative
percentage of each record (relative to each individual field).
Is there a way to rewrite it so I don't have to loop through each individual
record?
##### tdat is my data frame
##### j is my field index
##### k is my record index
##### tsum is the sum of all values in field j
##### tmp is a vector containing the values in field j
##### tdat[k,paste("cpct,j,sep="")] creates new fields "cpct1",...,"cpct5"
for(j in 1:5) {
tsum<- sum(tdat[,j]);
for(k in 1:nrow(tdat)) {
td<- tdat[k,j];...

I'm trying to create a list of point patterns ppp.object {spatstat} in a loop.
My dataset looks like this:

I''m developing a system similar to the ForumExample (http://
wiki.rubyonrails.org/rails/pages/ForumExample), and stumbled upon the
following.
Let''s say I wanted to get all the categories a certain user posted in.
How do I get that information withouth using a custom query
through :finder_sql (and thus losing the find_in_collection ownage)?
It would also be great to see how many

Operating on count lists of non-equal lengths
This is my first post to R-help and I look forward receiving some
advice for a novice like me...
I?ve got a simple repeated (4 periods so far) 10-question survey data
that is very easy to work on Excel. However, I?d like to move the
compilation to R but I?m having some trouble operating on count list
data in a neat way.

Deleting voicemail by program
Hi all,
I need to be able to delete a voicemail message using a program.
Is is sufficient to simply delete the .wav and .txt files in the spool directory?
Or do I need to also renumber the remaining files?
For example, let say a given mailbox has 20 messages in it and I want to
delete message number 5. Can I just delete the 2 files and expect that
asterisk will renumber them? Or do I
