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)

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]

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.

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:

2 ret = (int*) INTEGER(Ret); /* get pointer to R's Ret */
3 for(i=0; i<n; i++) ret[i] = data[i];

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.

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
