R help - Feb 2010 - playwith error message

Hi,

I'am using the playwith library to write my own small GUI application.
But I get the following error under Windows and Linux (Ubuntu):

Error in if ((modeOK %in% c("Identify", "Brush")) &&
(actions$ident == :
  Fehlender Wert, wo TRUE/FALSE n?tig ist

Under linux my R program simply continues, but under Windows it stops.
Since it is not in my code, has anyone an idea what goes wrong? I most
of the generated picture it is not possible to Brush or Identify.

Thanks in advance

Sigbert

Can you post a reproducible example that leads to this error?

This can happen depending on the exact graph type. You might want to
look at the playwith bug tracker [1].

Hi,

myplot <- function(x) {
  plot(x)
}

efaApp <- function(data, ...)
{
    playwith (myplot(data[,8:9]),
            click.mode = "Brush",
            )
}

efaApp(as.data.frame(Boston))

My plot routines even return invisibly a list itself.

I just saw that under Windows my program continues as well, just the
GTK+ window was minimized.

Thanks Sigbert

This does work if you use plot() directly:
efaApp <- function(data, ...)
{
   playwith (plot(data[,1:2]),
           click.mode = "Brush",
           )
}

My guess is that by passing through a custom function you generate
output that playwith does not understand. One way to work around is:

myplot <- function(x, ...) {
 plot(x)
}

Allowing for other options seems to make playwith happier.
