Dear all
I'm developing a grafical interface for Geneland that is presently one of the
R packages available.
My first question is about refreshing the interface while running a very long
process.
run<-function(){
tttry <- tktoplevel()
tkwm.geometry(tttry, "+200+200")
tkwm.title(tttry,"wait")
warn<-tklabel(tttry,image=imagepleasewait)
tkpack(warn)
tkfocus(tttry)
tcl("update")
print("Starting...")
validate <- 1
onIdle <- function(){
if (validate)==1){
Sys.sleep(0.1)
tkconfigure(warn,image=imagepleasewait)
tcl("after","idle", onIdle())
}
else
tkdestroy(tttry)
}
onIdle()
mcmcFmodel(...)
validate <- 0
}
If I remove the onIdle funtion the GUI stucks when I'm executing the
mcmcFmodel, if I leave it neves calls mcmcFmodel. Then I thought that there
could exist a fork() equivalent in R or somehow send a process to background
but I couldn't find anyway to make that with R-base package.
My second question is in which directory images are supposed to be packed?
R has a strict directory rules for packages and there is no documentation
regarding where should images for GUIs be putten. I was looking at SciViews
package and they distribute that under a directory called gui.
Best regards
Filipe Santos
