smooth scrolling with windows() function
Hi,
I have a large plot that I would like to display in a graphics device with
scroll bars. I therefore decided to use the windows function like so...
mag<- length(tick)
windows(height=mag/8, width=10, rescale="fixed")
However, when I use the scroll bars the device (i guess) is re-drawing the
plot. Is there any way in which I can get it to 'smooth scroll'?
Kind regards,

create a gui with a button to change graphic?
Hello everybody,
I am wondering if it is possible to create a gui to plot a time series
that is very big, it's an EEG signal of 20mins. What I would like to do
is plot the first 5mins, then have a button on the gui that plots the
next 5mins when pushed.
Is it possible?
Thanks in advance !
Gael.

graphing and scrolling
Dear R users
graphing with plot(x) seams to work for a small length(x), when length(x) is too large it seams to clutter the display, a solution would be to display subsets of x at a time, yet a better way which I hope R supports is to place a sliding bar on the display window to control length(x) and thus the resolution, which will involve auto scaling the y axis as well as automatically

bitmap images in tcltk
Dear R-help list members,
I'm writing a package using tcltk. Thanks to Peter Dalgaard's excellent
work on the tcltk package, almost everything has gone very smoothly. I'm
stymied, however, by the following problem:
I want to incorporate a bitmap image, stored as an xbm file, in a widget.
To take a simple example,
top <- tktoplevel()

Problem with ?curve
Dear all R gurus,
I have following syntax:
y = c(1:10)
chippy <- function(x)
{
y[5] = x
sin(cos(t(y)%*%y)*exp(-t(y)%*%y/2))
}
curve(chippy, 1, 20, n=200)
But I am getting error while executing :
Error in xy.coords(x, y, xlabel, ylabel, log) :
'x' and 'y' lengths differ

Excel
A common process when data is obtained in an Excel spreadsheet is to save
the spreadsheet as a .csv file then read it into R. Experienced users
might have learned to be wary of dates (as I have) but possibly have not
experienced what just happened to me. I thought I might just share it with
r-help as a cautionary tale.
I received an Excel file giving patient details. Each patient had an ID
