Hi, Is it possible to run R in command line to evalute R expressions and return results to stdout, something like >R CMD -e "R.version$minor" then you got return >"8.1" Or do a simple calculation >R CMD -e "sin(1.2)" >0.932039 Thanks. -- Pingping Zheng Department of Mathematics and Statistics Fylde College Lancaster University Lancaster LA1 4YF

Suppose I have a nx2 matrix of data, X, the following code generate density estimation for each column and plot them denlist <- apply(X, 2, density) par(mfrow=c(1,2)) lapply(denlist, plot) Does anyone know how to change the main title of each density plot to "var 1", "var 2" by passing optional argument "main"? I've tried lapply(denlist, plot,

Hello all, Would anybody tell me how to present spatial-temoral point processes in R, for example, I'd like to plot the spatial points in the sequence of their time domain? Cheers -- Pingping Zheng Department of Mathematics and Statistics Fylde College Lancaster University Lancaster LA1 4YF UK

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

Dear R people The function below should be decreasing, convex, and tend to zero when x tends to infinity. curve((1-pnorm(x))/dnorm(x),from=0, to=9) >From the plot we see that for x between 8.0 and 8.3 the function is fluctuating. As far as I understand, this is due to the function pnorm() not being sufficiently accurate in the tails. I am using pnorm() in a way that has probably not been

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

Derar R-people I have troubles understanding what the function sort.list() is doing. On the homepage it says that it returns a permutation which rearranges a vector into ascending or descending order (like order() but on a vector instead of a sequence). > sort.list(c(0, 2, 10, 11, 4)) [1] 1 2 5 3 4 which does not make sense to me. In fact I am getting the same (non-sensical) result using

Hi I'm looking to a function in R equivalent to S-PLUS' "interp". Is there any implementation in R? If not, is there any similar interpolation function such that at the data points the interpolated values concides with the data? Thanks in advance P.J.

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.

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

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 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

Dear R-devel During the last half a year I have several times encountered the following problem with optim() when using method= "L-BFGS-B". The function return a value which is clearly not the maximum (seen from printing the value each time the function is called). Some output is shown below. A few things I have observed (as I remember it): a. The problem seems to occur when the

Dear R-list I am having troubles understanding how the function is.numeric() works. Any help appreciated. Some commands are given here (the output and my comments are given below) vec <- c(1.4, NA, NA, NA) sapply(vec,FUN=is.numeric) is.numeric(vec[2]) is.na(vec[2]) is.numeric(NA) vec <- c(TRUE, FALSE, NA, NA) sapply(vec,FUN=is.numeric) is.numeric(vec[2]) is.numeric(vec[3])

Dear R-developers There is a discrepancy between the variables found by typing names(options()) and the variables described on the help page for the function ``options''. The following variables are in names(options()) but not described on the help page : "error.messages" "repositories" "show.coef.Pvalues" "help.try.all.packages"

Hi folks, I suspect this is a request for a sanity check than a bug report: I've been successfully compiling an optimised version of R for several years using the Intel compiler and MKL. I've just test-run the new Intel 15.0 compiler suite, and I'm seeing a few numeric failures that I don't see using the same build method with Intel 13.0. I've attached the output of

There is a bug in AIC.default and AIC.lm, as illustrated below. (I've only checked this under 1.6.1, and can't easily check if it has already been reported since the site is down.) > lm1 <- lm(y ~ x, list(x=1:10, y=jitter(1:10))) > lm2 <- lm(y ~ x, list(x=1:10, y=jitter(1:10))) > AIC(lm1, lm2) df AIC lm1 3 -18.662493 lm2 3 -7.265906 > AIC(lm1, lm2, k = 2)

Recieving digests. > RNGkind(NULL) [1] "Marsaglia-Multicarry" "Kinderman-Ramage" I would appreciate it if anybody has any comments on the following. Please do not comment on the R functions themselves, since they merely mimic a (bivariate simplification of a) C routine called from S. In particular, I would like to know if anything is available with regard to the
