[R] tkconfigure throws an error

[stephen bond]

When I do it with a function I lose the workspace. This is on a 
regulated matter and I MUST keep record of all commands/output from the 
source script plus the resulting workspace.

Thanks everybody.

Subj: RE: [R] tkconfigure throws an error

The command argument in the tkconfigure call should be a function, you
have the results of sourcing the file, probably not the correct thing.

Try something like:

tkconfigure(b1,command=function(...){source("./src/f.imm2.R")})


Hope this helps,
