w0 in legend
In Version 1.1.0 Under development (unstable) (June 8, 2000)
there seems to be a problem with an internal variable w0 in legend that
generates the following new error:
Error in legend((par()$usr)[1:2], (par()$usr)[3:4], Legend, lty = lty, :

lattice color problem with symbols: bug?
Dear useR's,
I have a problem with the lattice plotting of some symbols:

Error Bars
I'm trying to draw some error bars on a bar chart. I'm using code like
this:
thing <- c(3,3,3)
se <- c(1,1,1)
names(thing) <- c("A", "B", "C")
barplot(thing, ylim=c(0,4))
arrows(c(1:3), thing-se, c(1:3), thing+se, code=3, angle=90,length=0.1)
Using c(1:3) has 2 problems:
1. Obviously it is untidy, but using names(thing) doesn't work, and I

How to plot error bars
I'm a newcomer to R. I can't seem to find any documentation how to add
error bars to points in scatter plots. I guess I could plot the points,
then compute and plot line segments in the X and/or Y directions to
represent the errors?

discriminate analysis
Dear List,
I'd like to run a discriminate analysis on a data set, but have no idea
how to go about this in R. I have attempted to locate info in the manuals,
but may not be consulting the right sections or documents.
Can anyone point me to appropriate documentation if such exists.
Many thanks,

filed plot symbols
This example,

plot(x,y1,pch=21,ylim=range(c(y1,y2)),type="o",lty="solid",bg="white")

segmentation fault with 1D array (PR#500)
Here's a nasty one. The following has caused a segmentation
fault and possibly also a bus error.
fred <- 1:6
dim(fred) <- 6
dimnames(fred) <- list(LETTERS[1:6])
mm <- matrix(1:12, 2, 6)
mm %*% fred # segmentation fault here
In the case without the dimnames assignment the result is OK.
Cheers, Jonathan.

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

negative and positive values in diff. colors
Hi R-users,
I have a set of elevation residuals as geodata points. I would like to
display them in the following way:
-negative values using pch=20 (filled circle)
-positive values using pch=1 (empty circle)
while using the cex.max=5, cex.min=0.1 for points() to represent the
residuals value. Basically I would like to distinguish neagtive and
positive values at my map. How to do this.
Thanks

truncated multivariate normal
Please,
I would like to know how to generate a truncated multivariate normal
distribution k - dimensional, X ~ NT(mu, Sigma), where the
elements of X to be non-negative (except the first), and the first
dimension is strictly larger than zero.
Example:
X ~ NT_2(mu, Sigma),
where mu=c(0.5, 0.5) and Sigma=c([120, 191], [191,154]), with X_1>0
and X_2>=0

Std. errors of intercept and slope

I have the following output generated by linear regression. Since there is
only one regression intercept and one slope for one set of data, what is the
meaning of std. error for intercept and that of slope? Thanks in advance.

Symbols for male/female
Dear all,
I would like to use the biological symbols for male and female as plotting
symbols in a scatterplot (ideally filled and non-filled). R does not seem
to have these symbols using pch= in plot() nor are they implemented via
expression() or at least I did not find them. I found that the symbols are
e.g. available in the wasysym and the marvosym package in LaTeX.
