dotplot: character size of labels
Dear R users,
using dotplot (R1.2.0, WinNT4.0), I am trying to change the character size
of the labels of the points:

lattice: adding information on number of observations
Dear R-users,
I am using R version 2.9.1 and lattice 0.17-26 under windows.
In a lattice boxplot, I would like to add information on how many observations each singel boxplot is based upon.
For example (the basic plot):
# Begin R-code
library(lattice)
dat <- data.frame(panvar = rep(c("A","B","A","B"), c(3,7,4,6)), grp = rep(c("grp1",

read.spss (package foreign) and character columns
Dear R users!
I am using R Version 1.7.1, Windows XP, package "foreign" (Version: 0.6-1),
SPSS 11.5.1.
There is one thing I noticed with "read.spss", and I'd like to ask if this
is considered to be a feature, or possibly a bug:
When reading character columns, character strings seem to get filled with
blanks at the end.
Simple example:

within: order of newly added variables
Dear R community,
I am using function 'within' in R.2.9.1 to add variables to an existing data.frame. This works wonderful, except for one minor point: The new variables are added to the data in reverse order.
For example:
x <- data.frame(a = 1:3, b = 4:6)
y <- within(x, {
c = a^2
d = b^2
e = c+d
}
)
gives
a b e d c

each patient), I want to get the number of patients in the hospital on a
given date.
My data look like (simple example):

data mining: finding association rules
Dear R-users!
I would like to search for "association rules" (and compute support and
confidence, for example) in a data set, and wonder if this can be done with
R (version 1.5.0 for Windows)?
Particulary, I wonder if
a) anyone has done something like that with R
or
b)maybe someone has written an R-interface to some existing
algorithm/software (e.g. to something like the

replace text at certain positions in a file
Hello,
I am working with R version 2.10.1 under windows.
In a text file, I need to replace all characters at certain column positions with blanks.
For example, say the file contains two lines and looks like this:
ab34cd78e
fg3 hi78j
I'd like to replace everything at positions 3-4 and 7-8 with blanks, so the output should be:
ab cd e

I am working with R version 2.10.1.

lattice: left-aligned text in strips?
[adapted repost of question
http://tolstoy.newcastle.edu.au/R/e4/help/08/03/6260.html]
Dear R community,
by default, text in the strips of a trellis plot is centered in the
strip.
Is there a way to have the text left-aligned?
For example:
library(lattice)
test <- data.frame(x=rnorm(100), y=rnorm(100), a=rep(c("A: centered
text","B: centered text"),50))

putting reference lines or grids into the background of a plot
Dear R-community,
using R.2.9.1, how do you put reference lines or grids into the _background_ of a plot?
For example:
barplot(3:1)
abline(h = seq(0.5, 2.5 ,0.5), col = "red", lty = "dashed")
-> The lines are before the bars (and the line parts going through the bars might be considered as "chart junk", I suppose).
Now, in this toy example I could just do the

ISOdate() and strptime()
Dear R-people!
I am using R 1.8.0, under Windows XP.
While using ISOdate() and strptime(), I noticed the following behaviour when
"wrong" arguments (e.g., months>12) are given to these functions:
> ISOdate(year=2003,month=2,day=20) #ok

Dear R-users!
I am using R 1.7.0, under Windows XP;
I also have Internet Explorer 6.0.2600.0000, Norton AntiVirus 7.60.926.
Our firewall seems to want to "protect" me from downloading precompiled

apart from that I am not able to create appropriate help files.

AW: running Rcmd INSTALL, again
Indeed, there is no file named "dlltool" anywhere around here!
So, at last I am beginning to suspect that my collection of tools is
incomplete.
What I have got is "rw1020sp.zip" and
"http://www.stats.ox.ac.uk/pub/bdr/RWin/tools.zip". These are properly
istalled, I think.

Get calling channel before pickup
Hi,
Is it possible to get the remote channelname that will be bridged when
the call is answered, only having the channel that is in the Ring(ing)
state? As far as I can see no variable seems to fit when doing the show
channel command.
I want to be able to redirect/manipulate an incoming call before it gets
answered/bridged, but to do that I have to now which channel to use.
Is there a way?

lattice dotplot and graphic devices on Windows

After producing a lattice dotplot, I want to insert the graph into a
