TCL 2. closing the inspector

[rwoldford]

Closing the inspector can cause trouble. Again, this is long standing and I believe entirely in tcl.

Here is an example in R

Restarting R session...

library(loon)
Loading required package: tcltk
p <- l_plot(quakes$long, quakes$lat)

close inspector

layer switch default

library(maps)
NZFijiMap <- map("world2", regions=c("New Zealand", "Fiji"), plot=FALSE)
l_layer(p, NZFijiMap,

•     label = "New Zealand and Fiji",
  

•     color = "forestgreen",
  

•     index = "end”)
  

Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") :
[tcl] invalid command name "::oo::Obj230::my".

TRACEBACK:
