Renviron and Rprofile
Regarding user's home and working directories,
is Rprofile just an old name of Renviron?
or (can) should we have both files with different type
of definitions?
(talking about R.1.4.0 in linux).
Thanks

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:

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

Greyed text in the background of a plot
Hi!
Is there any way of having a greyed ("ghosted") text
(i.e, 2006) in the background of a plot?
I'm making a dynamic plot and would like to show the
year of each time step as a big greyed text in the background.
(the idea comes from Hans Rosling video:
http://video.google.com/videoplay?docid=4237353244338529080&sourceid=searchfeed
)

Recoding
Hi!
Given a vector (or a factor within a df),i.e. v1 <- c(1,1,1,2,3,4,1,10,3)
and a dictionary
cbind(c(1,2,3),c(1001,1002,1003))
is there a function (on the same line than recode() in car)
to get v2 as c(1001,1001,1001,1002,1003,4,1001,10,1003) ?
I'm using myself a function based on match() since
long ago (I think that thanks to advice by Prof. B. Ripley),
but would like to know if there

Log or diary file
Hi!
Is it possible to set a file to which both
commands and output would get automatically
saved? I've tried with sink(), but only get
the output. I mean something
like a combined history and sink, as you
get with File/Save to File.. in the windows
GUI.
Tis is done with diary filename in Matlab,
and you can state diary on and
diary off to control what is being saved to
the file.

zoo: variable gets modified at making zoo object

Renamig a factor
Which is the proper way to rename a factor?
If I do:
test$Parc[test$Parc=="Ol?rdola"]<-"Ol?rdola"
R complains that
Warning message:
invalid factor level, NAs generated in: `[<-.factor`(`*tmp*`, test$Parc
== "Ol?rdola", value = "Ol?rdola")

space between plots
I've set
layout(matrix(c(1,3,2,4),ncol=2))
and
par(mar=c(0, 4, 4, 0) + 0.0) and
par(mar=c(0, 0, 4, 3) + 0.0)
for the upper-left and upper-right plots, but
still get an space between both plots,
is there any way to completely eliminate that space?

day of the year for chron objects
Hi!
Is not there an standard R function to retrieve the day of the year
(since 1st Jan of the same year)?
I know I can make my own using julian, but find it weird that having
days(), months() etc doy() does not exist as an standard function.
Also, is the following not a bit inconsistent?
> a <- chron("20100506",format="ymd")
> a

Proportional axes
Hi!
If I'm plotting 2 variables with the same units
(i.e. wing length of 2 species), how can I force that X
and Y axes have the same size for length unit? For example, if
X ranges from 0 to 10 and Y ranges from 10 to 30, I want
Y axis to be twice as long as X axis. I know I can just
put xlim and ylim from 0 to 30, i.e.,
plot(runif(10,0,10),runif(10,10,30),xlim=c(0,30),ylim=c(0,30))

cutree() and rect.hclust(): different labelling of classes
I've found that while cutree() and rect.hclust() make the same classes
for a given height in the dendrogram, the actual labeling of the classes
is different. For example, both produce the same 4 classes but
class 1 according to cutree() is class 4 according to rect.hclust().
Would it be possible that future versions provide the same labeling?
rect.hclust() is useful to display the classes

as.numeric() and POSIXct format
Hi!
I'm confused by this:
> as.numeric(as.POSIXct(518400,origin="2001-01-01"))
[1] 978822000
I guess the problem is that as.numeric() assumes a different origin, but cannot find
any default origin.
How can I get back the seconds from the POSIXct format? In other words, which

I've tried as.numeric and unclass() using a origin=

query labels in iplot() (or other interactive scatterplot)
By Ctr-moving the cursor over a point in an iplot() scatterplot
(package iplots) it is possible to check the exact x,y coordinates
of a given point. Is it possible to check a text label for that point
as well? (i.e., the same info that would get printed on the graphic
using text(x,y, labels=v)
or with identify(x,y,labels), but I do not want to get the labels
permanently plotted on the graphic)
