Sometimes when working with tclArray's, an empty element called "active" is
appended to the array. Does anyone know when (and why) this happens? And
how to prevent it (or at least predict it so that it can be removed by
hand)?
E.g.,
library(tcltk); library(tcltk2)
tt<-tktoplevel()
dat<-tclArray()
tab<-tk2table(tt, variable = dat)
tkgrid(tab)
dat[[0,0]]<-5
dat[[1,0]]<-4
dat[[2,0]]<-56
tkdelete(tab,"rows",2, 8)
names(dat)
Any help would be greatly appreciated!
