Re: [R] Please Help
This is the R-help mailing list. See help(BATCH). You will need to write the required R commands in a separate script, say script.R and then execute it as R --no-save script.R logfile You may need to augment the code above to include directory paths etc. There are other useful documentations at http://www.r-project.org/ Regards, Adai Tanya Li wrote: Hello, I got this email address from http://tolstoy.newcastle.edu.au/R/e2/help/06/10/2516.html, I got started to use R recently, Can I ask you a question ? this is what I am using: platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status major 2 minor 4.0 year 2006 month 10 day03 svn rev39566 language R version.string R version 2.4.0 (2006-10-03) I wanna to call R in shell( bash ) , write all R commands in the shell script and make it a cron job to execute automatically. do you know how to do this ?

Re: [R] Please help with legend command

The legend box was so narrow that the line types that show up in that legend box look essentially the same, because they are short. I.e, although a line type might be a long dash followed by a short dash, only the long dash shows up in the box.

How do I stretch that legend box out so as to allow lty to draw longer line segments? Hi Phil, A quick hack is to get a copy of the function: sink(newlegend.R) legend sink() Get the file into a text editor and first get rid of the environment: namespace:graphics at the bottom, then change line 161 to: w0 - w0 + (4 + x.off) * xchar and line 212 to: seg.len - 4 source the new function: source(newlegend.R) and your line segments will be twice as long.

Re: [R] Please help.... i know its trivial
Patrick Callier napsal(a): rownames is the command you want, I think. rownames(A) - seq(1:8) Yes. More generally rownames(A) - 1:length(A[,1]) And keep in mind that nobody is going to help you next time, if you won't give a clear and informative SUBJECT in your message. Here it should have been something like 'wrong row names in subset' or 'dataframe subset question' etc, certainly not 'please help me, it's trivial'... Btw, there is something like the posting guide for this list (see footer).

However, if I add the line back in, the build fails. The file is only 14Kb long. Any help or suggestions are greatly appreciated. Thank you for your time.

Re: [R] Please HELP: Problem with BUILD command
As we have said to you before, we need a reproducible example, and it is very likely that you are speculating. There is no 'BUILD' command in R: do you mean 'R CMD build'?

It always says cannot find driver. All the examples use My SQL or some other program. I only have SQL Server by Microsoft. I know R might not have a native driver, but I have tried ODBC, too, without luck. If anyone can give me an example and hints on finding the driver that would be great! Thanks.

Re: [R] please help with estimation of true correlations and reliabilities
Dear John, I checked for the uniquenesses from factanal() and found out that these estimates need an a priori assumption about the number of latent factors (and they depend strongly on that assumption). What I want is an estimate of reliablity independent of such an assumption. Is it possible to specify such structure to sem or another SEM software?

RE: [R] please help with estimation of true correlations and reliabilities
Dear Jens, One of the nice features of maximum-likelihood factor analysis, implemented in factanal(), is that you can test for the number of common factors. More generally, the estimated uniquenesses will depend upon the number of common factors. Using sem() requires a stronger initial specification -- not only the number of common factors, but a prior specification of which variables load on each. If you make the model too general, it won't be identified. Furthermore, although I suggested that you use the uniquenesses to assess unreliability, the justification for this is clearest in models in which each variable loads on just one factor. I guess it would help to know a bit more about the application.

[R] please help with estimation of true correlations and reliabilities
Can someone point me to literature and/or R software to solve the following problem: Assume n true scores t measured as x with uncorrelated errors e , i.e. x = t + e and assume each true score to a have a certain amount of correlation with some of the other true scores. The correlation matrix cx of x will have its off-diagonal entries reduced by measurement error compared to the true correlation matrix ct of t, however the diagonal entries remain without attenuation. Consequently the correlation matrix of observed variables has different things on- and off-diagonal. I would like to estimate 1) the true correlation matrix ct 2) the measurement reliabilities rxx, i.e. the correlation of a score with itself attenuated by its measurement error (as if we had two measurements of the same score). but I don't have predefined asumptions about structure in the variable set as I guess would be needed for SEM.

RE: [R] please help with estimation of true correlations andreliabilities
Dear Jens, It sounds as if you're postulating a single-factor model underlying the x's (which is an assumption about the structure of the variables). If that's the case, then you could either use the factanal function in the stats package or the sem function in the sem package to estimate the model. The former would be simpler.

RE: [R] please help with estimation of true correlations and reli abilities
Jens I'm not sure what you intend by predefined assumptions. 1. If you merely want to conduct an exploratory rather than confirmatory analysis for the relevant paths, there are ways within SEM to do this. (In this case you could use John Fox's SEM package). 2. If you do not wish to assume multivariate normality, then you may use a variety of alternative (to maximum likelihood) estimation algorithms available in most SEM programs. 3. If you do not wish to assume either the outcome variable or the latent variable is continuous, there are SEM programs for this (Mplus being the most prominent.) 4. If you do not wish to assume the true score is a linear function (or generalized linear function for categorical variables) of the attribute being measured, then you have a more difficult problem. If presume you are familiar with SEMnet at http://www.gsu.edu/~mkteer/semnet.html.

Then you could use source(file.choose()) I've occasionally thought that file = file.choose() would be better than no default in a lot of functions that take filenames as arguments, e.g. file, the read* and write* functions, the bitmap device, Sweave, etc. Duncan Murdoch __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Please help with \usage{} for [.S3Class in Rd-Format
Dear all,
I try to submit a library to CRAN but can't overcome the last R CMD CHECK.
Can someone enlighten me how to put the \usage{} section for an S3-Method
extractor defined as
args(get([.refdata))
function (x, i = NULL, j = NULL, drop = FALSE, ref = FALSE)
NULL
I read the Writing R Extensions manual and know about
\methods{generic}{class}, however I don't get it right.
Please help
Jens

Re: [R] Please help with \usage{} for [.S3Class in Rd-Format
I think you may be trying too hard. Look at Extract.data.frame.Rd and
Extract.factor.Rd. I would just have an Extract.refdata.Rd.
You only need the \methods{generic}{class} notation when you want to
document a generic and a method, or more than one method, in the same help
file. And at present the Perl conversion does not cope with regexp
characters in function names

[R] please help me on this problem
Dear all: I am totally new to R, actually, statistics software.I get two very simple, even stupid question: 1) where I should put the data file in order to use it , I tried to build a work dir in library( package:base) and save the text file (data) there, then, I use read.table(filename), not work; I tried the full path, still not work. I must have done something wrong. 2) is it possible to create a data file in R instead of put data in a txt file and then save the file under R? I tried to find answer from the introduction, failed. I really appreciate your help, thank you very much. best __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help

It sounds like you need to carefully read the FAQ. help.start() the follow the Frequently Asked Questions link, and (if you're using R on windows) the FAQ for Windows Port then, I use read.table(filename), not work; I tried the full path, still not work. I must have done something wrong. Quite likely. But without more details, there's no way to say more. There isn't only one way to make a mistake, so there isn't one answer to it didn't work. Read the FAQ. It really does help. Read it carefully, and not in a frame of mind where you're saying to yourself I'll never understand this, this can't possibly help. You will, it can. 2) is it possible to create a data file in R instead of put data in a txt file and then save the file under R? Yes, after you've got a grip on the above. *After* the above is clear, read the help pages for save and load. Read the FAQ. I tried to find answer from the introduction, failed. But not the FAQ, presumably. I really appreciate your help, thank you very much. No problem. By the way, read the FAQ.

See the section called Basic method in http://www.psych.upenn.edu/~baron/rpsych/rpsych.html On 10/05/03 05:00, Yong Wang wrote: Dear all: I am totally new to R, actually, statistics software.I get two very simple, even stupid question: 1) where I should put the data file in order to use it , I tried to build a work dir in library( package:base) and save the text file (data) there, then, I use read.table(filename), not work; I tried the full path, still not work. I must have done something wrong. I'm surprised that it didn't work with the full path. I assume the error message indicated that it could not find the file, as opposed to some other sort of error. Relative paths work too. You don't say what operating system you are using, and it probably matters. But on Linux/Unix I usually start R from the directory where the data files are, and I have several of these for different projects. (Actually I use ESS, so I start R from within (X)emacs. When I say alt-x, R, I'm asked for a directory, and, if I'm not already in that directory, I enter it using a relative path name.) In sum, at least in Unix/Linux, you can put your data anywhere, and either you start R from where the data are or you use a relative or full path name. 2) is it possible to create a data file in R instead of put data in a txt file and then save the file under R? Yes, but this isn't the best way to do things unless the data file is pretty small. You can use c(). It is sometimes helpful to use matrix() with the argument horiz=T as in Example 2 in Advanced analysis of variance examples in http://www.psych.upenn.edu/~baron/rpsych/rpsych.html See also scan() - that is, look at the help for it. And you can also use edit(). For example: m1 - matrix(0,5,5) m2 - edit(m1) To save the object you've created, use write(), write.table(), write.matrix(), dput(), or save(). These differ in formatting and in how you read it back in.

So, please don't specify a stupid subject line, but a sensible one. (OK, the rest of this message's body is unspecific as well, hence the subject might be quite sensible in a way, tough.) 1) where I should put the data file in order to use it , I tried to build a work dir in library( package:base) and save the text file (data) there, then, I use read.table(filename), not work; I tried the full path, still not work. I must have done something wrong. The working directory is the one you are starting R in, or what you have set with setwd(). It's not a good idea to create a working directory within the library section. Specifying the full path should always work. What you did wrong is: - not reading the manual An Introduction to R carefully - not reading the manual R Data Import/Export - beeing to unspecific. After having read the manuals and help pages, you may ask a specific question, but including error messages and code you used (we cannot help if we cannot look at your mistakes). 2) is it possible to create a data file in R instead of put data in a txt file and then save the file under R? Yes. Exporting Data (including ASCII formats) is also covered in the R Data Import/Export manual. Uwe Ligges I tried to find answer from the introduction, failed.

[R] please help on frag polynoms
hi there, can anyone help me on the topic of frag polynoms? i just heard of a friend of mine, that i could build in a functioon called fragpoly (he was talking of such a function in the 'stata' language) in order to improve my process of finding an optimal linear model. instead of trying a vast amount of transformed inputdata to find the best fit and then step backwards down to e.g. rank 5 in order to get a smooth curve, i could start right from the beginning with only very few but therefore very flexible funktions (litle similar to box-plot) which adopt themselve automaticaly to an optimal fitt and r-squered. can anyone tell me if such a flexible adoptive function also exists in r+? (i could not find anything on the r+ pages with these search words). waiting desperately for help joerg __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
RE: [R] please help on frag polynoms
I'm guessing you meant fracpoly in Stata, which is fractional polynomial
smoothing. If that's the case, check out

Subject: [R] please help on frag polynoms
hi there,
can anyone help me on the topic of frag polynoms?
i just heard of a friend of mine, that i could build in a
functioon called fragpoly (he was talking of such a function
in the 'stata' language) in order to improve my process of
finding an optimal linear model.
instead of trying a vast amount of transformed inputdata to
find the best fit and then step backwards down to e.g. rank 5
in order to get a smooth curve, i could start right from the
beginning with only very few but therefore very flexible
funktions (litle similar to box-plot) which adopt themselve
automaticaly to an optimal fitt and r-squered.
can anyone tell me if such a flexible adoptive function also
exists in r+? (i could not find anything on the r+ pages with
these search words).
waiting desperately for help

I don't think there is anything currently available for fractional polynomials along the lines of -fracpoly- in Stata. You could construct an equivalent fairly easily using step(), or you could use local polynomials or splines. -thomas Thomas Lumley Assoc.
