Domain member (2k8R2) server, problem mapping Kerberos/NSS users
Hi list,
I'm trying to set up a simple fileserver (Samba 4.1.6 on Ubuntu 14.04)
as domain member, which delegates user authentication to AD (2k8R2) via

I have SSSD up and running and things like

I am new to speex and intend to port Speex to an SH3 based Single board
Application computer running at ~100 MHz. The application scenario is for
intercom kind of an Application.
I want to know if the CPU power on the SH3 based SBC running at ~ 100 MHz

as /usr/local/oracle8-client. Then I started R. After issuing install.

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

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

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

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

R commands from a text file ?
Hello
I was wondering if it was possible to enter R commands from an external
text file. If it is possible, it will be easy for repetetive tasks.
Does anyone have an idea ?

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):
