I'm just getting started with R, having a lot of original work on
modeling and exploring the shapes of time series to transfer from a
graphic LISP environment. Is there anyone in NYC that might be a good
tutor for me?

Dear R users,
This is a trivial question, there might even be an R
function for it, but I have
to do it many times and wonder if there is an
efficient for it.
Suppose we have a data frame like this:
d - data.frame(x=sample(seq(0.1:1, by=0.01),
size=100,
For each level of the factor in dotplot, I have time points I'd like to
connect with a line. In the example below, 'x' represents a starting
time and 'd' a duration, and I wish to connect 'x' to 'x+d'. Ordinarily
I would use Dotplot from hmisc for this, but I have not been able to
find a time
Dear Lister,
plot() is using the data range as the default limits of yaxis. Is
there any way I can change the limits? I just look at the help of
plot() and par() and couldn't find answers.
Thanks.

Hi,
I'm not sure I understand your question correctly, but does the ylim option
of plot do what you want?

If you look at ?plot.default you should find that the way to do this is to
use the ylim argument.

Hello,
I am new to R, and trying to work with it. I have a couple of quick
questions. First, I made a program and got the following error message.

Error in if
Try this:
print(p)
trellis.focus(panel, 1, 1)
with(z, panel.segments(x, as.numeric(y), x+d, as.numeric(y)))
trellis.unfocus()

Hi there,
I have a dataframe whose elements are numbers or
characters. I want to extract the frequencies of each
elements in the dataframe. For example,
d = as.data.frame(matrix(c(1, 2, 3, 3), 2,2))
What I want is first what are the elements in the data
(1,2,3 here) and second what are their
Here is one way; you create a vector of the data in the dataframe with
'unlist' and then use table:
d = as.data.frame(matrix(c(1, 2, 3, 3), 2,2))
d
V1 V2
1 1 3
2 2 3
table(unlist(d))
1 2 3
1 1 2

I can answer any question.
I don't know is an answer.
I don't know yet is a better answer.

Hi Jim,
This is the way to get the frequencies. But what I
want is to store the elements in one vector and their
frequencies in another vector. My problem is that when
I call table to return the frequency table, I do not
know how to extract these two vectors. I tried
table(...)$dinnames and it
