Dear R helpers

Function to "lump" factors together?
Sorry about the odd terminology, but I suspect that my intent might be
completely missed had I used "aggregate" or "classify" (each of which
appears to have some rather special meanings in statistical analysis and
modeling).
I have some data about software builds; one of the characteristics of
each is the name of the branch.
A colleague has generated some fairly interesting

Looking for simple line-splitting code
If I have this object:
x <- c("abc\ndef", "", "ghi")
and I write it to a file using `writeLines(x, "test.txt")`, my text
editor sees a 5 line file:
1: abc
2: def
3:
4: ghi
5:
which is what I'd expect: the last line in the editor is empty. If I
use `readLines("test.txt")` on that file, I get the vector

Suppress blanks/spaces in character
Hi all
I'm have a character vector and would like to suppress the blanks if there are more than one after the other.
Example:
Character value is: "abc def ghi"
The result should be: "abc def ghi"
I know that it's possible to delete the leading blanks with the command "trim". But how can I delete blanks within a character?
Thank you very much in

Looking for simple line-splitting code
Thanks to Rui, Peter and Tanvir! Peter's seems to be the fastest of the
3 suggestions so far on the little test case, but on the real data
(where x contains several thousand lines), Rui's seems best.

Arrange values on a timeline
I have a set of labels arranged along a timeframe in a. Each label has
a timestamp and marks a state until the next label. The dataframe a
contains 5 such timestamps and 5 associated labels. This means, on a
continious scale between 1-100, there are 5 markers. E.g. 'abc' marks
the timestampls between 10 and 19, 'def' marks the timestamps between
20 and 32, and so on.

Very simple traffic shaping script for H.323
Hello -
What I want to do seems very simple - I want to make sure any H.323
traffic gets processed before anything else entering or leaving this
network. The network has a videoconferencing device on the LAN at
192.168.16.4. A Linux firewall NATs an external IP Address to this
internal address and I have appropriate SNAT and DNAT rules that work.
The NAT and connection tracking rules all work

A 3rd option could be
scan(text=x, what="", blank.lines.skip=FALSE)
(all because readLines() doesn't obey the text=x convention, perhaps it should? I'm unsure whether the textConnection is left open in Rui's method.)

?nchar ?strsplit
Hi, my data frame is

I want to split my column ID using "/" as the place to split. How can I do that without telling the code how many sub-columns. I could use nchar(gsub("[^/]","",x$ID)) to get how many "/" are in each row of the column, but could

Hi,
this may be an obvious logical problem I'm not aware of, which cannot be solved
any more efficiently... but maybe it's just a bug or there is potential for
optimisation in Dovecot (or Thunderbird?).
When searching for multiple terms at once ("any of") with Thunderbird/Dovecot

break up a string into strings with a fixed length

I have some very long strings and would like to break up each long string
into multiple strings with a fixed length, e.g. to break up
abcdefghijkl
into
abc, def, ghi, jkl
I tried a couple of commands but was not successful. Any help will be
appreciated.
Best,
Jimmy
