Is there a simple way to assign values to S4 slots from within a function?
Doing this doesn't work:
assign_slot<-function(x){
assign("OBJECT@slot",x,envir=parent.env(environment())
}
assign_slot(x)
All I get from this is a new object with the name OBJECT@slot, the slot
assignment of OBJECT doesn't change.
I have thought about solutions such as eval(parse()) to pull this off, but
would prefer not to ugly up the code.
Thoughts??
I have searched rather thoroughly, but it is possible I overlooked
something. If I did, apologies.
I haven't tried this, but I would expect
OBJECT@slot <<- x
to work, assuming OBJECT already exists somewhere outside the function
but in its environment.
