Little graph questions!
I'm working up a set of small working examples in R to show what various
distributions are and the beauty of the central limit theorem. Those
example programs are in this directory:

You can feel free to use those if you want, or you can send me other
small working example code for R. The key here is small, self contained

Trying to make plot of several time series in same graph
Dear Friends in R:
On RedHat linux, R-1.1, I've gotten far enough to create the graph that
shows on the screen with 3 lines, but I have some trouble. Here is the
way I created the three "overlaid" graphs:
data<-read.table("DataCulture0",header=T,as.is = TRUE)
attach(data)
tmp1<-plot(acquaint~T,type='l', ylim=c(0,1),ylab="average

box doesn't surround words in legend in printed output
I have made a plot with a legend and on the screen it looks fine, but
when I save as jpg or pdf, or print, the legend box is too small, it
cuts through the words on the right side.
I put an example here:
http://lark.cc.ukans.edu/~pauljohn/R/apdftest.pdf
Is there a work around?

semi-parametric (partial linear?) regression
I just heard a talk about a semi-parametric model. I was quite excited
by the idea. This model is fitted
y= xB + g(z) + e
where x is a data matrix, B a column vector, z is another data matrix,
and g is a smooth model fitted by a Kernel Smoothing regression (I got
the idea any smoother would do as well).
The speaker said that when z is considered as a "control" variable, and

Trying to "pretty up" output from R job
Running R 1.1 on RedHat Linux 6.2.
I need to write a shell script that goes through a bunch of directories
of simulation output, creating summary files that have the mean and
standard deviation of the variables found in the data files in each
directory. I've got the R code doing almost the right thing. It reads
in data, then gets the mean and standard deviation for the numeric
variables,

Value lables, variable lables
I'm looking for an analogy to SPSS and "variable lable" and "value
lable" in R. I have a copy of S+4.0 and can't find any info in their
docs, and don't find it in R-intro either.
In SPSS, for each variable, there is a name like
VAR001
and a variable lable (a longer descriptive string) like
Respondent ID
and for many of the values of other variables there are

trouble getting output from graphs, again
It seems like every time I try to do something a little different, I
cannot get output saved just right.
This is on RedHat 7.2 with R 1.4.1.
The png output looks fine, but the eps output has the problem that the
bounding box on the legend cuts the legend in half. I put a copy of a
bad one here:

process all files ending in *.dat
On Linux (RH7.1) with R installed from CRAN rpms:
I have many files with miscellaneous names *.dat. I would like to
successively open each one, run some functions on them, and then write
some output numbers to *.summary. I have succeeded in doing this when I
type in each file name individually for the data input, but have not
found a way to search files in a directory and grab the *.dat. If

What is XGobi and what is it for?
I've seen XGobi come up in here from time to time, and I wonder what is
it, what is it for, do I need it? How about throwing me a bone here!

? building a database with a the great examples
Dear R help reader,
I'm not an expert in R and are lerning a lot by reading the help
digest, which is sometimes difficult because the huge amount of data
posted. I have posted some questions before, and are impressed how
quick I got a solution for my problem. Sometimes with quite different
suggestions. I was always wondering if my questions didn't come up
before. On the other site,

Processing all *.dat worked. Thanks
I got great, quick advice here earlier today. One little hitch was that
the pattern in list.files wants a regular expression, and *.dat was
grabbing all files with .dat in them, not ones ending in .dat. This
code creates a *.dat.summary file with the mean and std. deviation. of
the numeric variables for every *.dat file in the current directory.

New RH7.2 rpms for R-hdf5 support available
HDF5 is a high quality data storage format from NCSA
(http://hdf.ncsa.uiuc.edu/index.html) Marcus Daniels of the Swarm
Development Group has made available an R library called hdf5 which
allows loading and saving of data in hdf5 format. The source for his
library is here:

A couple of little R things I can't figure out (column percents, regression with lagged variables)
Simple usage questions that I ought to be able to figure on my own, but
can't.
1.I'm able to produce a cross tabulation table showing counts with
either table or xtabs. But I want column percentages for
interpretation, and it seems stupid to sit there with a calculator
figuring marginals and column percentages. How to make R do it after this:
> x <- c(1,3,1,3,1,3,1,3,4,4)

Hello,
Can anyone offer any insight on graphing classification dendrograms with
the nodes marked?
plot(tree()) produces a nice tree structure but there's no acccompanying

Systems of equations in glm?
I have a student that I'm encouraging to use R rather than SAS or Stata
and within just 2 weeks he has come up with a question that stumps me.
What does a person do about endogeneity in generalized linear models?
Suppose Y1 and Y2 are 5 category ordinal dependent variables. I see
that MASS has polr for estimation of models like that, as long as they
are independent. But what if the

nonlinear fitting when both x and y having measurement error?
Dear r-help,
I want to conduct nonlinear fitting to a data frame having x and y
variables. Because both x and y have measurement error, I want to
include error term of x variable in the model. I'm not sure but I
think ordinary nls model only consider error term of y variable.
How can I do this kind of nonlinear fitting in R. Is there any
examples in nls package?
Thanks in advance,
