So how would I get the following to work?

[1] 1

[1] 1 2 3 4 5 6 7 8 9 10

Error in foo(aa)[4:5] <- c(101, 102) : could not find function "foo"

I think the OP may perhaps want to define a method for "[<-" .
e.g. try:
methods("[<-")
If this is not it ... ??

As I understand it rownames(aa) returns a copy of an attribute of aa. So
changing the value of this vector should make the change to the copy of the
row.names attribute. I would then have to set the original row.names equal to
this copy to effect the change.
So my question is why "rownames(aa)[

I know how to define replacement functions in R (i.e. âfoo<-â <-
function(x,value) x<-value, etc.), but how do you define replacement functions
that operate on subsets of arrays (i.e. how do you pass an index into foo)?
For example, why does the following use of ârownamesâ work?
