I've spent hours trying to figure out the documentation and pouring over
Google and RSeek searches and am at an impasse. The documentation refers
to xmin, xmax, ymin, and ymax but doesn't say anything about them. The
only example gives them both as vectors, so I assume they refer to a
sequence of coordinates in which each rectangle's vertices is given by
(xmin[i],ymin[i]), (xmin[i],ymax[i]), (xmax[i],ymax[i]), and
(xmax[i],ymin[i]). But when I...

bar plot with non-zero starting level
Hi,
I want to plot grouped bars to compare 95% confidence interval estimates
from two models. Each bar represents a 95% confidence interval estimate
of a coefficient from one of the two models. Each group represents
confidence interval estimates of the same coefficient from the two models.
I think such a bar plot will nicely present whether 95% confidence
interval estimates of the same

In the code that I run (next lines), if I do not include the last three

Does anyone knows the solution of this problem or why this problem happens?

over/under flow
...e
that I am
porting is best left intact--so I need to query R somehow to the value
of OVER that causes exp(lgamma(OVER)) to equal Inf.
On my system,
exp(lgamma(171)) is about first to equal Inf.
I asked similar question a few weeks ago on exp(OVER) and got the
answer back as log(.Machine$double.xmax). I now have the lgamma
involved. I think that answer is what is OVER such the
.Machine$double.xmax = lgamma(OVER),
but I am not sure how to invert or solve for OVER
Thanks.

Abstract plot
I want to make a plot, but instead of showing _numerical_ values,
I would like to show _symbolic_ values.
For example, I want to plot a function y = a x + b, where
x varies between Xmin and Xmax. I would like the plot
to show, in the x-axis, the strings Xmin and Xmax, instead
of their numeric values. Is it possible?

abline; setting plot limits
Relatively new user with a question regarding abline.
I want to draw a st. line fit to some data but I want the line to span the
range of the x-data and NOT the plot limits.
In short the line spans xmin to xmax(of plot axis) but I want it to span
xmin to xmax (of x data).
Can this but done with abline or do I have to use lines and construct the
line from a+bx?

break error bars in ggplot2
...es including CIs as horizontal errorbars. I get an error when the scale limits are narrower than the boundaries of the error bar and hence the CIs are not plotted.
library(ggplot2)
df <- data.frame(resp=c(1,2), k=c(1,2), se=c(1,2))
ggplot(df, aes(resp,y=k)) + geom_point() + geom_errorbarh(aes(xmax = resp + se, xmin = resp - se)) + scale_x_continuous(limits=c(-1,3))
Is there a way to plot the errorbars anyway? Setting xmax to the scale limit is not so good, I guess, because you couldn't determine whether the CI is wider than the scale limits or not.
Thanks a lot,

selecting clusters of points
All:
Are there any functions out there for selecting all the
points in a region of a plot. I envision something like the
identify() function except one could circle a cloud of points (and
perhaps a vector would be returned of the same length as the points
plotted indicating logical membership in the circled cloud). Perhaps
someone has done something with the locator() function that would

Newbie graphing questions
Hi everyone. R is new to me and I'm very impressed with its
capabilities but still cannot figure out how to do some basic things.
There seems to be no lack of documentation but finding what I need has
proven difficult. Perhaps you can help.
Here's what I'm after:
1. How do I create a new plot without erasing the prior one i.e., have
a new window pop up with the new graph?

Accuracy problem in dchisq for non-central chi-squared
Hi,
I think I have identified a inaccuracy in dchisq when the non-centrality
parameter is non-zero and large. Here's a little test:
sys.dchisq.test <- function(N = 100000,mean = 0)
{
z <- rnorm(N,mean = mean, sd = 1)
x <- z^2
xmin <- min(x)
xmax <- max(x)
br <- seq(xmin,xmax,length = 101)
dbr <- br[2]-br[1]
hist(x,br)
p <- dchisq(br,df = 1,ncp = mean^2) * dbr
lines(br,N*p)
}
par(mfrow = c(2,1))
