The playwith solution is shorter but this GUI mockup using gWidgets might be
more flexible:
library(gWidgets)
make_plot <- function(i, ...) {
## your plot goes here
cat(i)
plot(1, i)
}
do_something <- function(i,..) {
cat("clicked on", i, "\n")
}
w <- gwindow("Plot example")
g <- ggroup(cont=w, horizontal=FALSE)
i <- gslider(from=2, to=100, by=1, cont=g, handler=function(h,...) {
make_plot(svalue(h$obj))
})
b <- gbutton("do something", cont=g, handler=function(h,...) {
do_something(svalue(i))
})
That will work with tcltk and RGtk2. If you have RGtk2 installed, then you might
also like this GUI template using traitr:
library(gWidgets)
options(guiToolkit="RGtk2")
require(traitr)
dlg <- aDialog(items=list(
i=rangeItem(value=2, from=2, to=100, by=1),
g=graphicDeviceItem()
),
buttons="Details...",
property_i_value_changed=function(., value, old_value) {
make_plot(value)
},
Details_handler = function(.) {
do_something(.$to_R()$i)
})
dlg$make_gui()
