Dear R-helpers,
I have a problem with the tcl "after" instruction. When I send:
> library(tcltk)
Loading Tcl/Tk interface ... done
> tcl("after",1000,cat("try tcl after\n"))
try tcl after
<Tcl>
the tcl command works fine. Similarly, the tcl command:
> tcl("after",1000,plot(rnorm(100)))
<Tcl>
works fine. But, if I send the command:
> tcl("after",1000,10^2)
<Tcl> after#0
appears a popup window which reports:
Error: invalid command name 100
Why?
