Solved: [Fwd: Matching failure in merge()]
I've found where the problem was and a way to solve this problem:
One dataset was encoded (and read) as UTF-8
and the other one was encoded (en read) as latin3
In this case, even if at the terminal you see
the same characters, R states that the two
elements are not equal.
Don't know if this is the way it has to be,
or this is a bug.
Anyway, editing the second file (encoded as latin3)

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?
Thanks

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.
Thanks

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))

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:

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

SVG format from any R graphic GUI?
I have problems with emf files because OpenOffice does
a poor job at importing figures in this format. On the other
hand, imported eps figures are not displayed, just printed.
Is there any R graphic gui able to export as SVG (or
other vector format)? I've
tried JGR, iplots and svGUI.
Thanks!

Connecting a gps to download data
I've installed through wine the program for a gps data logger QSTARZ.
The program works fine with wine, but cannot dowmnload the data from the
gps because I only have a windows driver for it.
Any way to get the windows driver installed in linux so that I could
download the data?

Subset: data frames and factor levels
Hi!
I'm doing:
etni <- subset(etni, NAMECOM!="Maniquisito")
where etni is a data.frame, NAMECOM a factor and "Maniquisito" labels
a row that I want to delete.
The problem is that while the row is deleted, the factor level is still
there (I can see "Maniquisito" if I do levels(etni$NAMECOM) ).
I know I can get the appropriate levels by:

For selecting ph, temperature and Ba I'm using:

if x is dataframe in which the only numeric fields are
in columns 2:5 ?
(using apply returns a character vector)
