I'd like to use lattice to make graphics under conditional structure like : if (TRUE) { barchart(....) dev.print(png, file = "image1.png", width = 600) } but there's nothing in the output file. It seems that it's too long to print graphic into the graphical output and the saved file is a blank picture. it works if I do that without the conditionnal structure. it doesn't

J'aimerais savoir si la fonction merge() est la seule disponible pour concatener des tableaux de donn?es? Est-ce normal que l'ex?cution soit lente?

Dear R users, I'm having trouble using aggregate() and would greatly appreciate your advice. I am using R 1.5.1 on Windows 2000. I want to call my function in the following way extract.data(x=dat[, "Age", "Year"]) where extract.data() uses aggregate() to count the number of cases for each combination of "Age" and "Year". I've defined

Dear users, is anybody of you aware of a R command to perform laplace transform or even its inversion? Thank you very much. Luca

My computer is a pentium 4 running at 2.4 GHz. My R is 1.7.1 I have written a program in R that calls C++. The program spends most of the time in C++ ( > 90% ). R basically deals with output and input. How slower can this be compared with the program I would get from rewriting everything in C++? Thank you.

Hi, I am running a loop to plot multiple plots. In s-plus, it shows multiple pages in the graphic window to allow checking on each plot. but in R, the next plot always overwrite the previous one, so i can only have the last plot produced, is there a way to have multiple pages in the graphic window just like S-plus does? Thanks

Hi, Suppose I have a multidimensional array: tmp <- array(1:8, c(2,2,2)) is there a function out there that, given a one-dimensional array index, will return the separate indices for each array dimension? for instance, tmp[8] is equivalent to tmp[2,2,2]. I'd like to derive the vector (2,2,2) from the index 8. thanks, Brad Buchsbaum

I have written the following function to calculate the weighted mean difference for univariate data (see http://www.xycoon.com/gini_mean_difference.htm for a related formula). Unsurprisingly, the function is slow (compared to sd or mad) for long vectors. I wonder if there's a way to make the function faster, short of creating an external C function. Thanks very much for your advice. gmd

I have had a visit from our windows buddy the BSOD twice in one day when running R1.6.2 under ESS5.1.24 on a win2000 platform. I wasn't doing anything special, just moving or resizing the emacs window, although I did have 4 or 5 emacs windows open at the time. Has anyone else observed this problem? Thanks, Darryl.

can you explain how it works? I tried to do like the example but it doesn't work

I've used "package.skeleton" and then I used "R cmd check" and it didn't work. can you help me?

I'd like to plot coefficients from glm result. with barchart, coefficients are ordered by the names of factors and I'd like to order them by values (or abs(values)). to do that, I've ordered the vector of coefficients but it's plotting the same thing. I'm working R 1.6.2 on win98. Thanks is it possible to do that with standard graphical function?

I'm using Rprofile file on R1.9.0 startup and inside I'm loading a personal Library which uses winMenuAdd() and I've got this error : Error in eval(expr, envir, enclos) : couldn't find function "winMenuAdd" I hadn't this problem with others R versions. What Can I do now to avoid that? I'm using R1.9.0 under Win98. [[alternative HTML version deleted]]

hi, for working with the simseg/acm approach i need multilm and it seems that the last version is 0.1-4.tar ? What's wrong in the description file, if i attempt install the package ? c:\DataMining\rw1062\bin>Rcmd Install multilm Malformed DCF file (file multilm/DESCRIPTION, line 6) [R1.6.2 /W2K] P.S. ..hmm a solution might be import the functions from multilm in my .Rprofile, but i

Hi, I have installed R1.6.2 on a Sun Sparc workstatioin 60 under Solaris 8. I' m using csh, tcsh or bash- shell. Unfortunately, it is impossible to use the "arrow-up" key on Sun's German keyboard to repeat a R command by using this key. Always following syntax error occurs: ^[[A Does anybody have a hint ?

Hi all, Here's a curosity I ran into since upgrading to 1.6.2 (precompiled for Windows). When using the chm help I get the following warning. I saw a recent post regarding this as a new warning (``dyn.load warning message in R1.6.2 on Windows XP'' dated 1/28/03), but not in the context of the help system. The warning only appears once and does not prevent the chm file from

I am participating in a project in the university, and appeared a doubt: if can I call one function from R as "solve" from C code. The intention of the research is to create a DLL. Is it possible and where can I find an example? Sorry for bad english! ___________________________________________________________________________________ Acesse nosso portal www.click21.com.br Porque

Hey, All Now I have a data set which is n-dimensional. And want to plot the Scatter Plot Matrix which is n by n. Does R have such function to achieve this? Thanks for your point. Fred

I am brand new to R and would like to know if there is a way to be able to create, save and retrieve a program in R like a script object in S-Plus. I am just not sure how to do this. I'm sure there are many ways to do this ranging from simple to complex, but the simplest way would be best for me. Thanks, in advance... __________________________________________________ Y!
