R-release.diff.gz: "patch detected! Assume -R? [n]"
Hi!
I'm upgrading to 1.6.2. (linux suse7.3).
I see that there is
a patch in R-release.diff.gz.
1. Is this patch stable? In other words, is
it adviced that I install R-release.diff.gz ?
2. When I do:
zcat R-release.diff.gz | patch -p1 -E
I get many lines such as:

Should I just accept the default

Passing an R matrix to a C program
Hello,
I'm starting to write a C function that gets
a list and a matrix from R. I'm using .Call
because I've undertood that this is recommended
to handle lists (am I wrong?). My problem is that I
can pass the matrix as a vector, but not as a 2D array.
For example, in the following simple C program:
#include <R.h>
#include <Rdefines.h>

3d in R
Dear R-users and R-developpers,
I've not been able to find 3d graphics in R, like
Splus spin() or brush(). Are there any that I've missed
and/or is anybody working on implementing these
type of functions?
Thanks

Subseting in a 3D array
Hi!
I have a 3d array:
> dim(ib5km15.dbc)
[1] 190 241 19
and a set of positions to extract:
> ib5km.lincol.random[1:3,]
[,1] [,2]
[1,] 78 70
[2,] 29 213
[3,] 180 22
Geting the values of a 2D array
for that set of positions would
be:
> ima <- ib5km15.dbc[,,1]
> ima[ib5km.lincol.random[1:10,]]
but don't find the way for the case
of the 3D array:

union of lists
Hi there,
Given 2 lists of integer vectors, i.e.:
> lista1
$"1"
[1] 1 34 5
$"2"
[1] 2 1
$"3"
[1] 3 10 15
> lista2
$"1"
[1] 1 5
$"2"
[1] 2 1
$"3"
[1] 3 10 29
I want to obtain the union of both, defined
as the union of the vectors, that is
lista.union[[1]] <- union(lista1[[1]],lista2[[1]]):

summary() and range(): inconsistency?
I've found the following and I'm kind
of confused:
> summary(delme)
Min. 1st Qu. Median Mean 3rd Qu. Max.
1 2950 5699 5756 8572 11680
> range(delme)
[1] 1 11675
summary() and range() give different Max. value for the same
vector!

S objects to R
I've tried to move objects from S to R.
In S+, I use data.dump() and data.restore().
I've made a file all.dum using
data.dump(ls()) in S+,
but the R command
load("all.dum") gives an error:
> load("/jaz/all.dum")
Error: restore file corrupted -- no data loaded
Is there any way to pass my objects from S+ to R?

convex hulls
Does anybody know if there are functions to:
1. Define a convex hull on a space with more
than 2 dimensions? chull just works for a plane.
2. Numerically select elements within a given complex
hull.

readline() to vector
Hi!
I'm trying to use readline() to ask for xlim() and ylim() values
for a subsequent plot. I'm doing:
lim <- readline("Enter xlim and ylim values: ")
then would like to use the values in lim for a plot:
plot(etc, xlim=lim[1:2],ylim=lim[3:4])
The problem is that lim is a character,i.e.,
"10,20,-10,50"
or
"c(10,20,-10,50)"
depending on the input to

R-gnome: no way to configure
Hi!
I've been able to configure and make R (1,4,0 linux)
except for the gnome support. I've checked all packages and libs mentioned
in R-admin.pdf (and by Luke Tierny) to make sure that I have them and even
using the following:
./configure --with-gnome --with-gnome-includes=/opt/gnome/include
--with-gnome-libs=/opt/gnome/lib --with-libglade-config=opt/gnome/lib
I still get:

Advice on long for loop
I'd appreciate advice on the following:
I've written an R function
that uses 3 vectors (temperature,
precipitation and potential evapotranspiration)
for a given site, calculates a water budget
(which implies few (<4) iterations), and, from
thresults of this water budget, calculates a number of
bioclimatic indices.
Now I want to calculate these indices
for a large number of sites

"load" for text file with functions?
Hi!
I'm writing down the methods that I used to
migrate from Splus to R and expand a bit the
R docs for this subject. Prior to send these
notes to the FAQ curator I would like to make sure
on the following:
Given an ascii text file with several
functions (i.e., myfuncs.txt), is there any equivalent to
load(), so that the functions become
usable in R? Or is it necessary
to install it as a

Problem with fitdistr for beta
I have the following problem:
I have a vector x of data (0<x<=1 ) with
a U-shaped histogram and try to fit a beta
distribution using fitdistr. In fact,
hist(rbeta(100,0.1,0.1)) looks a lot like
my data.
The equivalent to
the example in the manual
sometimes work:
> a <- rbeta(100,0.1,0.1)
> fitdistr(x=a, "beta", start=list(shape1=0.1,shape2=0.1))1)

R and 2 processors
As far as I can see by searching the archieves, R could not
take advantage of two processors in the same machine but there
were plans for implementing multithreading
in R. Is this work going on?
On the other hand, if two processors are
present in the same linux machine is it possible to focus one
processor on tasks of the operative system and the other
on R and/or other real computing? Could

Transforming matrix to data.frame: problems
Hi all,
I have problems transforming a matrix
into a data.frame:
If I do:

Why a does not have the same dimensions than

Problem with text() and pdf()
Hi!
I run a function in which I fit a linear
model, split the graphic window with
layout, plot the data and the linear fit to the left,
and the equation to the right using text() in this
way (probably there's a better way):
