Statemement by recurrence avoiding loop
Dear R users,
I would like to calculate a cumulative sum as following: on the i-th row, in the
j-th column of a matrix, I would like to obtain the sum of the (i-1) preceding elements of
this j-th column.
Could I avoid a "for" loop?
Thank you,
Tristan Lorino

GUI and Java: RSJava does not work
Hi,
About GUI and R, I would say that personnaly, I need to build a nice GUI for
people who does not know anything about R, to conduct simulations. I don't know
if the choice of R is the best. Maybe writing all the code in Java would be
better... I don't know.
That's why I have tried to install RSJava from Omegahat on my computer (Windows
2000). With R 1.5.0 or 1.5.1, I get the

Is it possible to install RMySQL package with R 1.5.0 on Windows 2000 platform?
This package is not listed in the packages list after calling "load package from CRAN" menu...
Thank you for your help,

Building a stand-alone package
Dear R users,
I'm working with Windows 2000 and R -- note that I could maybe work with Linux too...
I would like to know if it is possible to build a stand-alone statistical
package which:
-- could be programmed in R language,
-- could have a nice graphical interface with buttons and menus (this package
will be distributed to non-statistician people),
-- could realize statistical operations,

Library Tcltk
Dears users,
Thanks for your responses concerning my question of yesterday (about stand-alone
package). Il would like to explore two ways:
-- Tcltk extension,
-- Rweb application.
I have installed ActiveTcl (in F:\Tcl), and I have modified the PATH (in the
autoexec.bat file):
set R_LIBS=F:\R\rw1050\library
set PATH=%PATH%;F:\Tcl\bin
set PATH=%PATH%;F:\Tcl\lib

Deriv and integrate
Dear R users,
I would like to express a function (with only one argument) as the integrate of its derivate.
For example, for y=x^2, I would like something like
integrate(deriv(~x^2,"x", function(x) NULL, formal=T),0,2)
which would give me... 4.
Thank you,
Tristan

lme: how to compare random effects in two subsets of data
Dear R-gurus,
I have an interpretation problem regarding lme models.
I am currently working on dog locomotion, particularly on some variation
factors.
I try to figure out which limb out of 2 generated more dispersed data.
I record a value called Peak, around 20 times for each limb with a record.
I repeat the records during a single day, and on several days.

Habituation model
Dear all,
I am looking at habituation of dogs trotting on a treadmill.
I record the ground reaction force and I analyze it with several discrete variables (maximum, minimum,...)
For each variable, I get between 40 and 50 data per sample.
I record data at time 1 min, 2 min, and 4 min a day, and I have 4 days of measurement (one day a week).
That means I have 12 samples : Day1_Min1, Day1_Min2,

How to compare areas under ROC curves calculated with ROCR package
Dear all,
I try to compare the performances of several parameters to diagnose
lameness in dogs.
I have several ROC curves from the same dataset.
I plotted the ROC curves and calculated AUC with the ROCR package.
I would like to compare the AUC.
I used the following program I found on R-help archives :

random discrete from the first tuple
Dear UseR
I have a dataset, for instance x1(A, B, C), x2(M,F), x3(X1,X2,X3,X4)

know package e1071 can handle a random discrete,

How to compare areas under ROC curves calculated with ROC R package
I might be missing something but I thought that AUC was a measure for
comparing ROC curves, so there is nothing else needed to "compare" them. The
larger AUC is the higher correlation of 2 variables compared. No other
measures or calculations are needed.

Efficient sampling from a discrete distribution in R
Hello r-help,
As far as I've seen, there is no function in R dedicated to sampling
from a discrete distribution with a specified mass function. The
standard library doesn't come with anything called rdiscrete or rpmf,
and I can't find any such thing on the cheat sheet or in the
Probability Distributions chapter of _An Introduction to R_. Googling
also didn't bring back anything.

Go Bindings and govet
Hi Andrew, Peter,
I took a look at the results of running govet on the go bindings - there
are a lot of small/simple problems that should probably be looked at. Wrong
number of arguments a few times, shifts by > 32, etc.
