Here is my function:
setTurtle<-function(turtle,x,y,angle) {
if(angle!=turtle$angle) {
path<-"@c:/Docume~1/Owner/MyDocu~1/MyWork~1/MILAN/UNIHSR/R/turtle_bitmap/"
# select bitmap file (turtle000.xbm, turtle045.xbm, ...)
heading<-(45*(angle*180/pi+22.5)%/%45)%%360
file<-paste("turtle",paste(rep(0,3-nchar(heading)),collapse=""),heading,".xbm",sep="")
# redraw
tkdelete...
