similar to: process all files ending in *.dat

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. myDat<-list.files(pattern="*.dat$")

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: http://lark.cc.ukans.edu/~pauljohn/R/ExampleCode/ 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 things that

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

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? -- Paul E. Johnson email: pauljohn at ukans.edu Dept. of Political Science

Using RedHat Linux 7.0, R-1.2.2, R-hdf5-1.2 library, I want to load a dataset, do some stuff with it, then erase its objects, get an other, repeat. My friend wrote a function which tried to clear away all the objects. At the end, it uses rm() to remove objects. This is the same way we do it interactively, from the R prompt: testLoadSeveralHDF <- function(numFiles) { for (i in

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,

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 there is

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

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! -- Paul E.

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: http://lark.cc.ukans.edu/~pauljohn/ResearchPapers/meanProtest-box.eps When I asked about these

When I saw "SciGraphica": http://magnet.fsu.edu/~feiguin/scigraphica/screenshots.html I wished it could be a GUI frontend for R on Unix. -- Paul E.

Greetings Everybody: I generated a 1.2MB dta file based on the general social survey with Stata8 for linux. The file can be re-opened with Stata, but when I bring it into R, it says all the values are missing for most of the variables. This dataset is called "morgen.dta" and I dropped a copy online in case you are interested http://www.ku.edu/~pauljohn/R/morgen.dta looks like this

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)

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

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: ftp://ftp.swarm.org/pub/swarm/src/testing/hdf5_1.4.7.tar.gz I prefer to use RPMs to maintain software across many linux

Greetings I'm new to R. I became interested in it because my friends at the Swarm Development Team at the Santa Fe Institute have been using/developing R to work as a front end for HDF5 datasets. >From looking at the RPMS for R, I got the idea they were compiled without support for HDF5. Correct? If you are interested in the HDF5 data format and R, on my page I have RPMS for HDF5 and

You may want to take a look at a paper by Julia Kelsall and Scott Zeger in JRSS(C) - 1999, pp. 331-344. This paper describes a frequency domain approach to log-linear regression modeling of poisson-distributed count data, accounting for correlation and over-dispersion. There are also some S functions available to implement the methodology. Ravi. -----Original Message----- From: pauljohn at

Dear everybody: HDF5, a dataset formatting library, and R that is built with it, have been uploaded to ftp://ftp-fis.iarc.fr/pub/incoming.

I'm getting some abuse for asking about R-Gnome and I don't think it is fair. I did not create that project, I was just asking how it was going and whether that other project would help out. Now I'm getting some email that says some of you don't want a GUI interface because you think interfaces like that are inconvenient. OK. I agree, in most cases. I think GUIs for model

I have trouble understanding the R list object and how to add objects and get them out. I''m trying to collect snapshots with recordPlot and replay them. Got great help from everybody here yesterday on my histogram function, works fine to make the pictures: histomatic <- function (s1,s2,s3,var){ if (is.numeric (s2[[var]])) { par(mfrow=c(3,1)); rz <- range(s1[[var]],
