well,
for sure, one option is to trace the garbage collector gc() by a
function that enumerates the list of known objects and compares this
with its successor. But that's not reliable, as i can't really control
when to call the garbage collector. i also don't like to enumerate
objects and to compare these lists at each time step.
what else could be done?
cheers,
Thomas

Hello R users,
i'm wondering how to trigger variable creation.
Whenever a variable is created i want my own function myFun(...) to be
started.
if (exists("x")) {rm(x)} # after removal of x
# any of these calls
x<-10 # should call myFun
x=10 # should call myFun
assign(x,10) # should call myFun
etc.
# afterwards, each of the calls
x<-15 # should not call myFun
x=15 # should not call myFun
assign(x,15) # should not call myFun
etc.
Has anyone an idea? Unfortunately, this feature is also missing in the
library trackObjs.
regards,
Thomas
