Dear All,
Many thanks to Marc Schwartz and Gabor Grothendieck who have explained
me about using expand.grid function and clearly explain how to use
JGR.
dd - expand.grid(interface = interface, screen = screen,
computer = computer, available = available)
There are several possibilities
hi
using plot(..., las=1), i.e. horizontal axis labels, the labels on the
y-axis jams if the heigth of the graphics windov becomes too low
while both x-axis and y-axis kind of removes superflus lables with las=0
(default)
is there a way to make plot behave alike with horizontal lables?
regards

Hi!
I have strings where occasionally some -chars occur.
How can I delete these chars?
I tried it with gsub but using as replace does not
work.
Thanks a lot for any hint!

You can fit negative binomial using the 'zicounts' package
library(zicounts)
data(teeth)
names(teeth)
## c) fit negative binomial regression model
nb.zc - zicounts(resp = dmft~.,x =~gender + age,data=teeth, distr = NB)
nb.zc
Even,
library(zicounts)
library(Fahrmeir) # use
thanks
with 'jams' i meant messes up, but your term overlap is exactly what i
actually had in mind
though a minor problem, do you think that the code will change to enable
checking for enough height-wise space?
regards søren

Thanks for the reply, Andy!
My problem was that I could not get rid of a double
quote character within the
string. I don't know what I have done before, but now
it works...?!?!
Sorry for bothering you.

I have some compiled code that works under winXp but not under linux (kernel
2.6.10-5). I'm also using R 2.1.0
After debugging, I've discovered that this code:
#define NMAX 256
long **box;
...
box = (long **)R_alloc(NMAX, sizeof(long *));
gives a null pointer, so subsequent line:
Dear Adaikalavan,
Your solution (the second function) is definitely the most elegant and
generic solution of all replies in this discussion. Robust for missing
values and flexible to allow as many calculations as desired! It is so
clear, I even managed to hack it (of course also thanks to the

Hi list!
Debuging one of my R programs I found:
0 * NA
[1] NA
It this a bug, or intentional? I would expect 0 or 0.0 depending on the type
of the NA.

I believe that's intentional. NA means we don't know what the value is, so
just about any operation with NA will result in NA. You might think
anything times 0 is 0, but:
0*Inf
[1] NaN
and there's no guarantee that the true value not observed is not Inf...

I have uploaded version 0.96-1 of both Matrix and lme4 to CRAN. The
source package should migrate to CRAN over the weekend and binary
packages should be available some time next week.
As for previous releases, the versions of these two packages are
interdependent. The lme4 package requires
Hi R-help,
I have a database of 10 students who have written an overall of 78 essays.
The challenge? I would like to identify who wrote the 79th essay.
Has anybody used R in this context?
Even if not, would you suggest me which pattern recognition technique I might
possibly apply?
I assume that you know the usual procedure is to 'score' each essay by a
vector that gives the frequency of occurrence of commonly used (sometimes
adding subject matter specific) words and phrases. This multivariate
response is then fed in as a training set into your favorite supervised

You will need to escape special characters. Here is an example :
my.string - Here is a quote \ in a string

Not that I am aware of. Try library(help=maps) for a list of all the
functions in the library. Anyhow, I am not sure that a US map with zipcodes
will look very good/readable, unless you focus on a very small area (i.e.
county).
