R:how to separate stuff?
Thanks for your help on moving files from
S+ to R and on attaching directories.
If attaching directories is NOT possible in R,
is there any other way to separate
objects into different folders or something similar?
For example, to keep user functions for multivariate
analysis in a different "place" than user functions on
time series, or to keep data objects of project_1
in a different

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]]):

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:

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

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

Problems with make pdf (R-patched_2002-07-15.tar.gz)
After configure, make and make check on
a linux Suse 7.3 box, I run
make dvi and make info with no problems but get

Is this normal? Is there a bug in this part
of the installation?

"X11 font at size 16 could not be loaded"
Hi,
I'm using plot.lda (R1.4.0 on linux) and,
if dimen > 2, I get the error:
Error in text.default(x, y, txt, cex = cex, font = font) :
X11 font at size 16 could not be loaded
The traceback indicates that the problem
comes from pairs(). I've tried several
cex and font values, always with the
same error.
The same command works fine with pdf()

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

Bib. reference on R
I know I've seen the answer to this question
but could not find it now:
What's the appropriate(s) general reference(s)
for the "R language and environment for statistical computing and
graphics" that should be included
in a scientific article?
Thanks

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:

summary() and range(): inconsistency?
I've found the following and I'm kind
of confused:

1 2950 5699 5756 8572 11680
> range(delme)

summary() and range() give different Max. value for the same

"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

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:

> fitdistr(x=a, "beta", start=list(shape1=0.1,shape2=0.1))1)

graphics in batch mode

modes,.."

and, although I get no errors and
the output file with the results is
written to disk, I get no graphics.
