Can R make an usual dotplot
Dear R experts,
Can R make an usual dotplot just like Minitab and other softwares?
I have the following data, and can use dotchart to graph a dotplot:
y=c(2.873438152e-01, -8.732895642e-01,
4.579001889e-01, 1.047395204e+00,
8.491182299e-02 , -1.938007105e+00,
-1.273708343e+00, 9.848010588e-05,

dotchart vs. dotplot ... groups
I'm trying to create a dotplot with some grouping.
I've been able to create what I want using dotchart (basic graphics), but can't quite get it using dotplot (lattice). I prefer to use lattice (or ggplot2) because I think it's a bit easier to control some other aspects of the plot appearance.
Basically, w/ lattice I've not been able to get the y-axis label to include the

Order of Dotplot output
I'm just learning to work with R, and am having some difficulty controlling the output of my dotplot.
The default order of the function dotchart seems to be the largest value on the bottom and the smallest on the top. I wanted it in the opposite order (which is how my data frame is currently sorted), so I used the following approach, which works
orderidx <- order(b2000$RR)

plotting confidence intervals
Hi R People:
If I have a fitted values from a model, how do I plot the
(1-alpha)100% confidence intervals along with the fitted values,
please?
Also, if the intervals are "shaded" gray, that would be nice too, please?
I check confint, but that doesn't seem to do what I want.
Thanks in advance,
Sincerely,
Erin

dotchart {graphics} 2.11.1 vs. 2.12.1
I have a factor vector of subject races (Asian, Black, Hispanic, White; n=30) that I want to plot with a Cleveland dotplot or dotchart.
I tried the following in R2.12.1 :
> dotchart(table(school$Race))
Error in plot.xy(xy.coords(x, y), type = type, ...) : invalid plot type
Using the same data set in R2.11.1 the operation succeeded (I tried several variations to be sure):

confidence-intervals in dotchart
My earlier posting should have said "dotchart", not "barchart".
1) How does one show confidence-intervals in a "dotchart" and use rownames
for labels on the y-axes? I have looked at "plotCI" in "gregmisc" package .
But it does not seem to produce something like a dotchart. The statistic,
error, upper-bound, and lower-bound are in a

Dear R People:
Is there a library for Multivariate time series, please?
For some reason, I'm thinking that Dr. Paul Gilbert may have one?

Dotplot: y-labels from rownames
How can I use row.names() as y-labels in Dotplot? How to set horizontal

I have a vector xx:

dotchart questions
I am trying to put 3 dotcharts side-by-side with minimal space between
each. Each chart is for a different variable, but the vertical axes are
the same.
I want to have vertical axis labels on the lefthand chart but no
vertical axis labels on the other two. Plus, I would like very little
space between charts 1 & 2 and between charts 2 & 3.
I have one approach but am not too happy with

Cent. Mov. Ave
Dear R People:
Here is an interesting question(I think)
Suppose I want to calculate Centered Moving Averages; i.e.
x[1] <- ( sum(y[1:12]) )/12
x[2] <- ( sum(y[2:13]) )/12
and so on.
Of course, this is easily done through loops. However, I have
been trying to do this more elegantly, but have failed. I have
tried things like
j1 <- 1:109
j2 <- 12:120
x[1:109] <- ( sum( y[j1:j2])

Can R produce dot plots like the one of the following picture:

Julia set in R

Has anyone produced code for a Julia set, please?
It's not all that tough to do, just thought I'd check before
re-inventing the wheel.
Thanks,

function via source or fix
Hello R People:
Suppose I create a function, x.e, via the fix command:
> x.e <- fix(x.e)
When I type in x.e, the function code appears, along
with the name/number of the environment.
However, if I create a function, y.e, and source it in, when
I type in y.e, the function code only displays(no
environment).
Why is this, please? (It's not a bug....I just wondered).
I am using
