registering Fortran routines in R packages
Thanks for your email.
I try to change the name in lowercase but it conflicts with a C implementation also named halton. So I rename the C function halton2() and sobol2() while the Fortran function are HALTON() and SOBOL() (I also try lower case in the Fortran code). Unfortunately, it does not help since I get

registering Fortran routines in R packages
Dear list,
I?m trying to register Fortran routines in randtoolbox (in srt/init.c file), see https://r-forge.r-project.org/scm/viewvc.php/pkg/randtoolbox/src/init.c?view=markup&root=rmetrics.
Reading https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Registering-native-routines and looking at what is done in stats package, I first thought that the following code will do the job:

64-bit integer type warning on windows
Dear list,
During the last two months, I spent a lot of time trying to remove the following warnings of my package randtoolbox:

sscanf(params[0], "%" PRIu64 "\n", &inp_mod);

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

registering Fortran routines in R packages
Have you tried using tools:::package_native_routine_registration_skeleton()? If you don't like its output, you can easily edit its results and still avoid most pitfalls.
Cheers, Jari Oksanen

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

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",

R tutorial
Dear all,
I have just found a 'good' tutorial R for datamining. I think it
should be on the contributed docs.
http://cran.r-project.org/other-docs.html
Here is the link
http://www.liaad.up.pt/~ltorgo/DataMiningWithR/
What do you think?
Kind regards

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

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)

[R-SIG-Mac] rnorm.halton
Hi all,
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
beginner in Fortran...
Does someone already do this for his package?

attach
Hi all,
I have a question regarding the memory usage for the attach function.
Say I have a data.frame inputdat that I create with read.csv.
I would like to know what happens on the memory side when I use
attach(inputdata)
Is there a second allocation of memory for inputdata?
Then I'm using eval on a expression which depends on the columns of
inputdata. Is it better not to use attach

An update of the Distribustions man page
Dear list,
I would like to suggest a small update the ?Distributions man page of the

I think it would be better to put in this man page a link to the CRAN task

extended Kalman filter for survival data
If you mean this paper by Fahrmeir: http://biomet.oxfordjournals.org/cgi/content/abstract/81/2/317 I would recommend BayesX: http://www.stat.uni-muenchen.de/~bayesx/.
BayesX interfaces with R and estimates discrete (and continuous) time survival data with penalized regression methods.

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

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
