I'd like to check within a whether an argument is a formulae of the type ~X or similar. What's the right way to do so? I'm using: is.language(obj) but not sure this is right Thanks in advance P.J.

After "image" and "persp" would it be interesting to als have contour as a generic function?

This depends whether you want to compile the packages yourself (here you need the extra tools) or just install the pre-compiled versions (here you don't need them). I would guess that most of the Windows users just do the latter and the installation is then straighforward by using the option "Packages" on the top menu. You can donload/install from CRAN or from a local zip file.

Hi When preparing documentation using Rd2dvi sometimes we get "overflow" on some lines. The consequence is that in the documentation there are some lines where words are not hyphenated or moved. The final document has some lines with more columns than the rest of the text. This happens when we use \code{} (which probably calls the \tt in latex). I've been checking the documentation

Hi I'm installing R with the standard commands: ./configure make make check make dvi to create DVI versions make pdf to create PDF versions make info to create info files make install make install-dvi make install-info make install-pdf Everything works fine apart from "make

In an email to the help list John Chambers wrote about the function helpSilent which is in the methods package, pointing out that there is no restrictive reason to be in this package. I did not know about this function and just incorporate it in several functions of the geoR package where a much less elegant solution was being used. I guess other packages could use it as well. Therefore,

Dear R people We have two packages, where the first package (geoR) is required by the second (geoRglmm). Both packages have functions calling C-code via .C(). We would like to call C-functions included in the first package from within the C-code in the second package. Is this possible? An appropriate header file was included in the src directory of the second package but this alone did not

Hi all, I face the following problem. I have two variables x,y. I have also calculated the surface z. When I am drawing the surface with function >levelplot (in library lattice) everything is OK. I have the legend etc ... Then I am trying to plot x,y on the same graph. So I am doing : >points(x,y) But, the points are not in the correct position. They are a little bit shifted to the

Dear R members, Is there a way I can include more than one variable in a histogram? Many thanks in advance, Liqing, Liqing Zhang Department of Ecology & Evolutionary Biology 321 Steinhaus Hall U.C.

How would you proceed with the following problem: I have an data frame containing a table relating raw scores on an iq test to 'decile-like' scores. data<-data.frame(age =c( 8, 9, 10, 11, 12, 13, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70), pers90=c(33, 39, 43, 47, 50, 54, 54, 52, 50, 49, 47, 46, 43, 42, 39, 37), perc75=c(27, 31, 37,

Hi I'm writing my MSC and I've used R to do the data analysis. Now I want to make a reference to the program but I don't know how ! I thought of something like: Anonymous. 2001.

Dear all, I'm writing a lgrind definition for R. Lgrind is a program to produce pretty program listings for inclusion in LaTeX documents. Does anybody here have any experience with lgrindefs?

Dear all, There has been some time since I asked about interpolation in higher (>2) dimensions, and I must admit I failed to write a function to do this myself the last time, but eventually ended up doing it in MATLAB. I tried to translate the MATLAB code, but MATLAB code is so much more opaque than R (S) code, so I failed that too, mainly because I could only get one MATLAB session, I would

Dear all, I am interested by the various messages sent to the r-help mailing list these last few days about documentation on R. Yet, there are a lot of issues actually open on this topic, and it is not clear to me what is the "urgent need for documentation" on R. R comes with the 'Introduction to R' by Venables et al. I recommend the colleagues and students in my lab who are

Dear all, I have been trying to understand what runif() is telling me. I am generating lots of numbers (billions and billions (wow, I''ve dreamed about saying that for many years... :-) ), for a distribution that has the following quantile function: 1 / (2 * sqrt(1 - p)) (that is, the distribution has a lower cutoff) As you can imagine, this has rather heavy upper tail. I was

Sorry, I pasted the wrong file in earlier... this is the correct one: pValCalculator(b, n=20, m=20) { ind <- 1:min(c(n,m)) prob <- (1-pnorm(b,sd=std*sqrt(ind))) prob1 <- sum((n-ind+1)*(m-ind+1)*prob) prob1 } inputData <- scan("/users/lvssso/projects/LAMA/output/pValLamaScore.tmp", list(block1 = "",block2 = "",width1 = 0,width2 = 0,alignment = 0,score

I am trying to install R on a unix workstation (Sun-SPARC) but I am not sure which of the binaries to use. The only binaries available are for linux, nextstep, osf, and windows. Which one of them will work for a SUN sparc station?? Thanks. PS. I tried to compile the source code but it looks like I have a probelm with fortran. So, if I could install one of the binaries it would be a lot

Hi Rers, W/o trying to make a long story short (I hope you read that correctly), I have been working on a nice little R function ... Somewhere along the line I got an error that refers to a max function in my function (I think this is a vector vs. scalar issue): Error in max(..., na.rm = na.rm) : invalid "mode" of argument If that's not bad enough, even when I q() R and say
