Logical test and look up table
...r with 63 levels). I would like to associate each name with a
particular Type (coded as 1,2,3,4,H or H1) in a second column. Is it
possible to do a lookup table of associations (i.e. A23 is of type 1, A13
is of type 3 ...) so as to fill up automatically the $Type column.
df()
$Source $Type
A23
A24
A9
A32
A25
A14
A10
A12
A11
A13
G
Alternative solutions are also welcome.
Thanks in advance
P.S. I found a discussion mentioning match() and %in% but it does not seem
adapted.

strange strsplit gsub problem 0 is this a bug or a string length limitation?
...113.
Is it due to a string length limitation in R or is it a bug in the strsplit
or gsub functions, or in my string?
I'd very much appreciate any suggestions

How to get all possible combinations?
Dear all, suppose I have a vector with elements as:
Vec <- c(2,3,4,5,6)
Now I want to have all possible combination of length 3 using those
elements and without any repetition. Like, I want to have 1
possibility like 2-3-4 but not 3-2-4.
Can somebody guide me how to achieve that in R?
Thanks for your help.

Indexing within scan
Dear R-help subscribers,
Can some one please help me figure out how to write code that will allow me to use a for loop to scan a number of files one by one, and then save a summary of each file as the for loop progresses. For example I have 24 files named a1 through a24, and I want to do something like:
results<-numeric(24)
for (i in 1:24)
{
p<-scan("ai.txt") # where the i is an index for each of the 24 files
results[i]<-mean(p)
}
Thanks for any help,

Upgrade from 2.2.8a to 3.0.0 fails
Hi,
I tried to upgrade samba on a Linux from 2.2.8a to 3.0.0, and after the
upgrade the printer sharing fails. I would like to participate in the
search for the bug (if it is a bug), but I don't know how to start.
If this is not a bug I would like to know why not, and how to work
around, that the printer does not work with the attached smb.conf, while
it works with samba version 2.2.8a

RFC3389 support issue with DG104S
I am getting (with older image):
RFC3389 support incomplete. Turn off on client if possible
How do I turn that off for the DG104s? Or if I can't how do I tweak
asterisk?
I see posts about ATA-186's having an audiomode, but the closet I came
to was inbanddtmf. I tried =0 and =1, no effect.
Thanks!
