horizontal violin plots?
I am trying to make horizontal violin plots. I have tried both vioplot and simple.violinplot, but both of them seem to not be willing to take the horizontal option. Is this correct, or am I just bungling it somehow? For instance, for vioplot (from the example shown, with the horizontal modification): > vioplot(bimodal,uniform,normal, horizontal=TRUE) Error in median(data) : need numeric data

Reading text files and readLine
Hi, I am trying to write a function to read in a whole text file as a single string ( so I can calculate its "sha1" hash function using package "digest"). I need a single string containing the whole file, and so far I was using paste(readLines(fileName), collapse = ""). Unfortunately this function gives me warnings : incomplete final line found by readLines on

Unexpected error "subset assignment" (bug?)
Hi, I run into following problem. It seems to me that operation in the 3rd line should be valid. > b = matrix(as.raw(0), 8,8) > q = as.raw(1:8) > b[1,] = q Error: incompatible types in subset assignment > length(b[1,]) [1] 8 > typeof(b[1,]) [1] "raw" > length(q) [1] 8 > typeof(q) [1] "raw" Is this a bug or a "feature"?

Error list and debugging R code
Hi, I am trying to debug my code and looking for any tool to help me out with it. My main problem is with the error messages I can not figure out where they come from (what function produced them) and what do they mean. Is there such a think as list of error messages produced by R and standard R packages, and what do they mean? Or any tool to extract information which function produced the

FYI: Problems while loading package "class (VR)"
Hi, Today, I performed automatic updates of packages and somehow lost "class" package. I loaded a library that depended on it and got: Error: package 'class' could not be loaded In addition: Warning message: there is no package called 'class' in: library(pkg, character.only = TRUE, logical = TRUE, lib.loc = lib.loc) I tried to load it by instal-package: class (VR) and

Casting in R
Hi, I am looking for functions that would allow me to access raw binary data of R vectors. One way would be to use: x = (1:10)*pi writeBin(x, "temp.bin") r = readBin("temp.bin", "raw", n=length(x)*8) Other to write my own C code. Is there any other simpler way?

Is.integer and testing for integers
Hi, I was trying to figure out if there is a function in R that tests if R object contains only integers. I though "is.integer" would be it, but this function only checks "whether its argument is of integer type or not". As a result x = (1:5)^2 is.integer(x) Returns false. Of course I can write my own function like "!any(x!=as.integer(x))" but I am just trying to

Sum of logical vector
Hi, Recently I was told by users of some of the function I wrote that they experience crashes in places where logical vector was passed to sum function. However on my computer those functions work just fine. After closer look at documentation of function 'sum', I realized that it is defined only for complex and numeric vectors, so I guess I was using "undocumented feature".

Splitting the string at the last sub-string
Hi, I need to split a string into 2 strings, with the split point defined by the last occurrence of some substring. I come up with some convoluted code to do so: str = "Chance favors the prepared mind" sub = "e" y = unlist(strsplit(str,sub)) z = cbind(paste(y[-length(y)], sub, sep="", collapse = ""), y[length(y)]); y z z[1] z[2] Is there a simpler way

boxplot, notches, etc.
Sorry to repost this, but it looks like it's getting buried in r-help (originally posted October 5: my experience says that if it hasn't been answered by then it won't be). I wouldn't bother, but I'm worried that r-devel might be better, *and* a previous e-mail of mine on the subject in January also seemed to get buried. Synopsis: boxplot notches look weird when notches are

Passing character strings from C code to R
Hi, I have a C code which produces array of integers and potentially a string, and I have problems passing the string out. Here is the relevant part of the code: 1 PROTECT(Ret = allocVector(INTSXP, n)); 2 ret = (int*) INTEGER(Ret); /* get pointer to R's Ret */ 3 for(i=0; i<n; i++) ret[i] = data[i]; 4 Free(data); 5 i=1; 6 if (comment) { // comment was found 7 n

Unexpected results from sort function when partial and index are used
Hi, Consider the following example: sort(10:1, partial=3) ## 1 2 3 7 6 5 4 8 9 10 sort(10:1, index=T) ## $x: 1 2 3 4 5 6 7 8 9 10 ## $ix: 10 9 8 7 6 5 4 3 2 1 sort(10:1, partial=3, index=T) ## 1 2 3 7 6 5 4 8 9 10 The first 2 calls gave expected returns; however, the third one did not returned an index as requested. I could not find anything about it in

Questions about readBin function (Was: dec2bin?)
Hi, The latest version of R had some changes to functions "readbin() and writeBin() [which] now support raw vectors as well as filenames and connections.". As a result I am working on retiring "raw2bin" and "bin2raw" functions from "caTools" package which do exactly the same. Thanks to Prof. Ripley for bringing this change to my attention. Which brings me

Looking for function for Double to raw to double conversions
Hello, I am trying to implement function for reading/writing some XML file format. One feature of that XML format is that a lot of binary data is stored in Base64 format, and since R's XML package does not seem to support it, I just wrote my own converter from "raw" format to Base64, and back. However one place I have problems with is conversion from vector of doubles to vector of

Release of new version of caMassClass package and new package caT ools
Hi, A new version of "caMassClass" package was released today. The package contain pipeline for processing and classification of protein mass spectra data. The main change is off-spinning from the library collection of generic functions into a new package "caTools". This package, which might be useful to broader group, is much smaller than "caMassClass" and has fewer
