X11 resources
Would it be hard to make the X11 device driver in R accept general X11
resources? In particular I would like to be able to set the title of
the graphics window when I start it up. (Note this is not the same
thing as the title of a plot but rather is the character string
visible to the window manager, and usually goes in a titlebar on top.)
For example in Splus one can do

Scheme in R
The initial authors of R said?, "...we implemented the language by
first writing an interpreter for a Scheme subset and then
progressively mutating it to resemble S." Further on in that article
they elaborated that their strategy was to create a parser that would
take expressions in S-like syntax and translate them to Scheme
S-expressions.
Does R still work that way? Can R be made to

porting R package to Splus
I am considering getting the rpvm package for running a parallel
virtual machine working on Splus. That package contains a
considerable amount of C-level code written to interface R with the
pvm3 library functions and of course all of it uses the R macros and
conventions associated with the R-style ".Call".
It looks as though it might be possible to automatically transform
that code to

ylab in time series plot (PR#2869)
You get a warning message when you specify a ylab parameter while
plotting data whose x's are POSIXct values. Apparently the
`axis.POSIXct' method tries to reset the ylab---via the ...
parameter---after it has already been set by higher level methods.
Here is a function that illustrates the problem.
ylabProblem <- function() {
x <- ISOdate(2003, 4, 1:10) # POSIXct

Help with functions as arguments
Hi,
I am trying to write a function which defines some arguments, then uses those arguments as arguments of other function calls. It's a bit tricky to explain, so a simple example will have to suffice. I imagine this has a simple solution, but perusing through environments and other help lists has not helped. Suppose I have two functions:
f1 = function(a)
{
b = a + 1
b
}
f2 =

legend order in ggplot2
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_a",
"name_c". I'd like to legend to present in the order: the "name_b" at the
top, and "name_c" at the bottom.
As a consequence, the legend is indeed in the order:

barplot default colors
Dear R-help,
Can some one explain why barplot() uses changing colors in the bars by
default? I should think that most of the time when people draw barplots,
they want the bars to be in the same color. (At least that's what I'd
expect. The first time I used barplot() in R, I was shocked to see the
colors.) As an example, one example in ?layout draws a scatterplot with
histograms drawn

masking functions
Dear all
I was writing some code that needed functions from packages 'MASS' and
'CircStats', and I received a warning saying that the function
'eqscplot' in one of the packages was masked by another 'eqscplot' from
the other package (in fact 'eqscplot' from 'CircStats' seems a short
version of 'eqscplot' from 'MASS'). This masking of

I am trying to analyze some of my data using linear discriminant analysis.
I worked out the following example code in Venables and Ripley
It does not seem to be happy with it.

Plotting densities
Hi group,
I am currently plotting two densities using the following code:
x1 <- c(1,2,1,3,5,6,6,7,7,8)
x2 <- c(1,2,1,3,5,6,5,7)
plot(density(x1, na.rm = TRUE))
polygon(density(x2, na.rm = TRUE), border="blue")
However, I would like to avoid bordering the second density as it adds
a nasty bottom line which I would like to avoid.
I would also rather have a dashed or dotted line

Change the legend order by order function
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_c",
"name_a". I'd like to legend to present in the order: the "name_b" at the
top, and "name_a" at the bottom.
Could it be done by order function or its inverse?

legend order in ggplot2
Hi
Your approach seems to me rather complicated. I would reshape data before plotting and maybe also change order of levels in resulting variable factor
library(reshape2)
dfm<-melt(df)
dfm$variable<-factor(dfm$variable, levels=levels(dfm$variable)[c(2,1,3,4)])
p2<-ggplot(dfm, aes(x=rep(1:2,4), y=value))
p2+geom_line(aes(linetype=variable))+

Regression lines for differently-sized groups on the same plot
Hi there,
I've looked through the very helpful advice about adding fitted lines to
plots in the r-help archive, and can't find a post where someone has offered
a solution for my specific problem. I need to plot logistic regression fits
from three differently-sized data subsets on a plot of the entire dataset.
A description and code are below:

legend order in ggplot2
Hi,
I ran your code, but the results were not as expected. After I ran the
code by "source", it return
No id variables; using all as measure variables

and no line or legend is on the graph (as attached)
Am I doing anything wrong?

Help with Plot/Legend
Dear R-Users
I have 2 questions:
Firstly, If I create a matplot and legend for multiple vectors and then tag
another vector on using matlines (e.g. a 'total' of all vectors), is there
anyway to add the new line to the legend without recreating it? I have
created the plot this way because I would like to define the lty and lwd for
the 'total' vector so that it can be

nesting scale_manual caracteristics in ggplot
Hi there,
I am having a little problem with combining three scale_manual commands in a
facet plot. I am not able to combine the three different characteristics,
instead ending up with three different descriptions next to the graph for
the same geom. I would like to see two separate labels (not three); one
describing lines 1-7 and the other 8-14. For each of the treatments (A-B) I
want a
