generic methods - in particular the summary function
Hi all,
I'm currently working on the fitdistrplus package (that basically fit
distributions). There is something I do not understand about the
generic function summary.
In the current version on CRAN, there is no NAMESPACE saying
S3method(summary, fitdist)
.
However if we use summary on an object send by fitdist function it
works fine...
According to R-lang, we have

legend with small colored boxes
Hi all,
I tried to a nice legend with small boxes filled with the colors used
for the plots. But it does nor work, boxes are always filled with black.
An example is here
plot(1:4,1:4)
lines(1:4,4:1, col="blue")
legend("top",leg=c("a","b"),col=c("black","blue"), fill=TRUE)
How could I specify the colors? the argument col.box is the

AR(2) modelling
Hi useRs,
I'm trying to fit a basic AR(2) model with the 'ar' function. And when
I try to check the value of the coefficients, I could not find the
same value as the 'ar' function.
Here is my example:
myserie <- c(212, 205, 210, 213, 217, 222, 216, 218, 220, 212, 215, 236)

rowSums, rowMean and rowCumSums?
Dear list,
Don't you think it could be useful to have in R base a function
rowCumSums, that compute cumulative sums for each row of a matrix?
My implementation of rowCumSums is
rowCumSums <- function(x) t(mapply(function(row)cumsum(x[row,]),
1:NROW(x)))
I'm sure it can be improved to have other arguments like na.rm or dims.
Is there any hope to have this function in R?

problem with symbol function
Hi all,
I use the symbol functions to draw circles. But the argument lty does
not work on windows but works correctly on my macbook:
x <- -4:4
y <- -4:4
plot(x,y,type="n")
symbols(0, 0, add = TRUE, circles = 1, inches = 1, fg="black",
lty="solid")
symbols(0, 0, add = TRUE, circles = 1, inches = 2, fg="black",
lty="dashed")

constrained optimization
Dear list,
The task view on optimization does not reference a package for non linear
constrained optimization problems. Stefan Theussl told me to look at the
Rsolnp package, but unfortunately it is not very clear what method is R
ported. (The authors ported the matlab code of Yinyu Ye

on the optim function
Dear useRs,
I have just discovered that the R optim function does not return the number of iterations.
I still wonder why line 632-634 of optim C, the iter variable is not returned (for the BFGS method for example) ?
Is there any trick to compute the iteration number with function call number?
Kind regards

An update of the Distribustions man page
Dear list,
I would like to suggest a small update the ?Distributions man page of the
stats package. The current version contains the following line.
The CRAN package \pkg{SuppDists} for additional distributions.
I think it would be better to put in this man page a link to the CRAN task

thousands separator
Dear useRs,
I was wondering how to deal with data where thousands separator is a space
or a comma? with google, I thought I found the answer but the thread (
http://tolstoy.newcastle.edu.au/R/help/06/04/25524.html) just focuses on
decimal separator.
Is there any function to numbers written like this in a csv file?
Thanks in advance

R-/Text-editor for Windows?
Tinn-R (http://www.sciviews.org/Tinn-R/) is one of the topmost
suggestions when googling an R-(text-)editor for Windows. However,
to me it appears dissappointing that Tinn-R does not handle utf-8
(mac-roman, or any other) encoded R-scripts or, in general, text
files. Besides Emacs and the R built-in editor, could you
recommend a good editor for Windows, even some commmercial for a

S. function calculating x +- y
Hello, I am looking for an elegant one-liner for the following
operation:
x <- rnorm(10)
y <- runif(10)
c(mean(x)-mean(y), mean(x)+mean(y))
I thought about
apply(data.frame(x, y), 2, mean)
but I don't know how to apply the +- operation on the result of
apply. Thanks, *S*

sample() from (un-)sorted vectors
Hello,
Vector y is an alphabetically sorted version of vector x. Will both
samples, X and Y, be "absolutely" random or will they have systematic
differences? And: Should I sort or shuffle a vector before sampling?
Thank you, *S*
x <- as.factor(LETTERS[sequence(10:1)])
y <- sort(x)
X <- sample(x, 5)
Y <- sample(y, 5)

From numeric vector to string vector
Hi there, I have a numeric vector let say:
Vect <- c(12.234, 234.5675, 1.5)
Now I want a string vector like:
changedVec <- c("012.234", "234.568", "001.500")
Would be grateful if somebody help me how can I do that.

Apply functions along "layers" of a data matrix
Hello
How can I apply functions along "layers" of a data matrix?
Example:
daf <- data.frame(
'id' = rep(1:5, 3),
matrix(1:60, nrow=15, dimnames=list( NULL, paste('v', 1:4, sep='') )),
rep = rep(1:3, each=5)
)
The data frame "daf" contains 3 repetitions/layers (rep) of 4 variables
of 5 persons (id). For some reason, I want to calculate

Patch to add Beta binomial distribution. Mentor needed!
Hello,
I implemented the Beta binomial distribution following the patterns of the
binomial distribution code and inspired by JAGS' code [1]. I have studied
the code carefully but it's my first run in the R internals.
Can somebody review the code and if everything it's ok commit to the
repository?

I need to transform classic 32bit Fortran code to 64bit Fortran code,
see the discussion [R-SIG-Mac] rnorm.halton. But I'm clearly a

Does someone already do this for his package?
