barchart for aggregated (sum) data in lattice?
Hi list,
I have data in a dataframe t1, with a column for different amounts
spent, a column what it was spent on, and a column with dates, from
which I create a new column with months.
Example:
amount <- rep(c(10,20,30),3)
what <- rep(c("food","books","cycling"),3)
when <- c(rep("2008-09-05",5),rep("2008-10-07",4))
t1 <-

get function to return object "name"?
Dear list,
I've written a function that plots subjects. Something like:
myplot <- function(subject) { plot(subject) }
Subjects are vectors, e.g. ...
s1 <- c(200,200,190,180)
... and plotting them works fine, e.g. ...
myplot(s1)
Now I want to have "s1" etc appear in the plot title, but I don't know
how to refer to this generically (the object "name"? I tried

Manage several graphical devices in interactive mode
Dear R-users,
Does anybody know a good way to create and use several graphical devices at
the same time in interactive mode? Ideally, I'd like to open 2 to 3 devices
and assign names to them. This way, I could make any
addition/modification/update to a particular device using its name.
I did not see anything like a name argument in ?X11. Is there an
alternative?
Thanks in advance for your

ggplot, qplot: alpha channel for colors corresponding to factor
Hi,
I have a qplot like the one in the minimal example below, except I
also have faceting like this:
qplot(jitter(Goodall),jitter(Better.adapt),colour=Second.adapt,facets=~Pol,data=d1)
and with the real data I get quite a lot of overplotting, so I would
like to add an alpha channel.
In addition, I would like to be able to control which colors are used
for each value of Second.adapt (which

Arguments to "personalised" plot()
Hi Folks,
I'm curious for an explanation of the following -- it's a
matter of trying to understand how R parses it.
I've written sundry little "helper" variants of functions,
in particular plot(), to save repetitively typing the same
options over and over again.
For example:
plotb <- function(x,...){plot(x,pch="+",col="blue",...)}
This does exactly

Pie chart and labels
With a pie chart
pie(c(11, 15, 16, 29, 31))
how can I generate labels for the chart, such as
orange: 11
green: 15
blue: 16
red: 29
purple: 31
rather than the default labels that are drawn automatically

Startin R from .RData in linux
Hi!
Is it possible to start R by clicking
the .RData file in linux as in Windows?
I've tried with ubuntu hardy using
the right button and selecting R, but does
not work. Is there any way to set it up?
(I know R can by started from the terminal,
selecting the appropriate directory).
Thanks

ggplot: order of numeric factor levels?
Hi,
I'm having problems with qplot and the order of numeric factor levels.
Factors with numeric levels show up in the order in which they appear
in the data, not in the order of the levels (as far as I understand
factors!)
Here is a minimal example:
library(ggplot2)
y <- c(-1,2,0,0,-2,-1)
z <- factor(y,levels=c(-2,-1,0,1,2))
qplot(z)
For me, the resulting plot is ordered: -1,2,0,-2

Rank Values in a Matrix
Dear All,
a short and maybe simple question:
I have to rank all values in a matrix from 0 to X,
[1] [2] [3] [4]
[1] 0.1 2 0 3
[2] 50 3 3 1
[3] 100 1 1 0
[4] 100 2 2 0
0->0
0.1->1
2->2
3->3
50->4
100->5 (X=5)
is there any function for this? i have looked in several packages
(vegan, labdsv etc.) because I am working with species by site tables,

I don't know how to run a r-code written in emacs
Hi,
I just installed R, I'm work in UBUNTU and I don't have idea about how to
run a r-code written in emacs
into the shell.
Well I am in a shell, and obviously I can run simple commands over there,
Must I compile the program? if yes, How must I do that?
what is the extension?
I really appreciate your help

Saving functions
Hi,
Appologies for the simple nature of this question, I am unable to find
the answer in manuals (EG and introduciton to R).
I have written a function in a text editor and saved it with an .R
extension. It is saved in my working directory. How can I run it, do I
need to use source? If so, how do I supply the arguments to the
function? Or does it need to be saved in a particular directory?

include scripts into main file (the LaTeX way)
Dear R-people,
I want to use an idea from LaTeX in the work flow with R.
It is possible in LaTeX to have a main file from which other files are
called (ie included).
So for example if you have book, the main index file would call each
chapter separately.
Is there something comparable in R that follows the above 'include' idea
from LaTeX?
A main file that calls parts of an analysis or

Problem going back to a viewport with gridBase
I am setting up base plots -- one in viewport A and and one in B. This part
works fine. But if I go back to A after having done B and add
horizontal lines it seems
to not use the correct coordinates. How do I tell it to resume using A's
coordinates? I am already using par(fig = gridFIG()) but it seems that that's
not enough to reestablish them. What happens is that when I go back to

Can't read a binary file
Hi, I've read up on readBin() and chapter 6 in the R Data Import/Export manual, but I still can't read a binary file. Here is how the creator of the file described the code that would be needed in Fortran:
"Every record has a return in fortran. The length of each record is nx*ny*4. To read you would use the following:

Nestad ANOVA with random Factors
Hi,
I need a help. I am new in R and I need to run a nested anova with fixed and
random factors (Mixed Model). I have a design with three factors: Day, Area
and Plot and the dependent variable is density. The factors Day and Area are
fixed while Plot is random, factor Area is nested in factor Day, and factor
Plot is nested in Area.
I can do it using aov by:
