Hey there, I?m quite lost in the R tcltk package and would love to get some help. My problem is this: Total_substes = 5 # example subcounter=1 # while the maximum number of subsets is not reached put buttons onto the tt widget while (subcounter <= total_subsets) { ??????? subname paste("subset ", 1:total_subsets, sep "") ??????? subnameasstring2 <- subname[subcounter] ??????? toString(subnameasstring2) ??????? subname.button = paste("subnameasstring2",".button", sep = "") ??????? subname.button <- tkbutton(tt,text=subnameasstring2, command=function() iconfigure(vhight, vwidth, vanzheight, vanzwidth, total_number_iplots_onscreen, subcounter)) ??????? tkgrid(subname.button) ??????? subcounter = subcounter +1 }?????? I create dynamic buttons but when I press them the value of i.e. subcounter is overritten by the last value assignment Button subset_1.button gives me in this case when I press it 6 and that?s obviously wrong because it should be 1. Has anybody an idea how I can solve that? Btw: The goal is to spread isets onto the screen (but a lot of them)
