plot: abline() - define line length
Hi,
is there a way to define, that a line drawn via abline() should only
go from for example -2 to 1 on the x-axis (with something working
similiar to xlim()) ?
thanks for any help!

Problems copying some files from windows to linux
Hi,
This might not be entirely samba server related, but the problem I am
experiencing is affecting a planned implementation of a new Samba
Server, and from the smbmount man page, it appears that this is the
recommended list to reqest help - so hopefully someone might be able to
assist :-).
I am running a Debian Linux machine (kernel 2.6.0) with Samba 3.0.1

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

ggplot2 geom_rect(): What am I missing here
Hi R fans,
As a newbie following the five-hour rule (after hitting my head against
the wall for five hours, post to this list), I am appealing for some
help understanding geom_rect() in ggplot2.
What I want to do is very simple. I want to generate a plot of
rectangles. Each one represents a business cycle. The x-values will be
pairs representing the start and end of each cycle. The y-values

ggplot2 will not draw a rectangle. Error: ggplot2 doesn't know how to deal with data of class XXX"
What am I missing? When I run the code below I get the error message
"Error: ggplot2 doesn't know how to deal with data of class function"
Googling suggests a message of "Error: ggplot2 doesn't know how to deal with data of class XXX" is not uncommon but I don't see why I am getting a "function" error unless I am using some reserved word?

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

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?

Setting the colors of lines in a trellis plot...
With some help from those with expertise on this list, I managed to
produce a plot using trellis that looked like I wanted it to look.
Now, I need to take the same plot and make the lines on it color, but
I want to specify the color for the lines myself.
I've managed to make the key use the colors I want. I've managed to
make the symbols of the actual plot use the colors I want. But I

Error with repeat lines() in function
I have a function that does some plotting. I then add lines to the
plot. If executed one line at a time, there is not a problem. If I
execute the function, though, I get:
Error in ans[[1]] : subscript out of bounds
This always occurs after the second lines command, and doesn't happen
with all of my data points (some do not have errors). Any ideas?
Thanks,

converting csv to image file
Hello everyone,
I want to get a 1km by lkm grid raster image using my csv data. If I call
latitude=a, longitude=b and preciptation=c.
a<-(1,2,3,4,5)
b<-(6,7,8,9,10)
c<-(10,20, 30,40, 50)
Then I found an example in r help which goes like

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 =

colored PCA biplot
Hi-
I'm trying to make my PCA (princomp) colored. In my csv excel sheet, I have
the first column numbered according to the groupings I want to assign to the
PCA. I've played around with trying to set this first column as the color
vector, but haven't had any luck.
Any suggestions? Thanks,

2D Random walk
I've wrote some code to simulate a random walk in 2 dimensions on a lattice.
Basically I want to add something in to make it plot it point by point so
you can see what is going on.
Heres my code for the random walk in 2d
RW2D<-function(N)
{
i<-0
xdir<-0
ydir<-0
xpos<-vector()
xpos[1]<-xdir
ypos<-vector()
ypos[1]<-ydir
