Using tcltk or other graphical widgets to view zoo time series objects
The playwith package might help, though if I understand the problem
correctly, the help(xyplot.zoo) example is not so relevant. If you
want to switch between many series you could use a spin-button or
somesuch. To execute a function you can create a button.
If you have a hundred-column dataset like
dat <- zoo(matrix(rnorm(100*100),ncol=100), Sys.Date()+1:100)
colnames(dat) <- paste("Series", 1:100)
Then this will give you a spin button to choose the column to plot,
and a button to print out the current series number.
playwith(xyplot(dat[,c(1,i)]), parameters = list(i = 1:100,
do_something = function(playState) print(playState$env$i))
)
Note that the playwith package uses RGtk2, and therefore requires the
GTK+ libraries to be installed on your system.

There is an example of using zoo together with the playwith package at the end of the examples section of help(xyplot.zoo) which may address this. On Thu, Jan 28, 2010 at 7:10 AM, Research <risk2009 at ath.forthnet.gr> wrote:
Dear all, I am looking at the R-help entry below: http://finzi.psych.upenn.edu/R/Rhelp02/archive/26640.html I have a more complicatedt problem. I have a zoo time series frame with 100+ sequences. I want to cycle through them back and forth and compare them to the 1st column at any time. I need also a button to click when I need the viewed-selected sequence (that is being compared to the 1st column one) to be manipulated (by some algorithm or be saved individually etc. etc.)... I am trying to modify the code at the above link but somehow I can not make it to work with zoo time series objects. Any help would be greatly appreciated.
