I've not seen an actual answer to this, which is that this is a
misunderstanding as to how NextMethod works.
First,
+ x - unclass(x)
looks wrong. NextMethod uses the next method at the call to the generic,
and subsequent changes to the object 'x' do not alter the class that would
be
Can someone help me understand the following behavior of [- ?
If I define a simple class based on a matrix, the [- operation only
inserts into the first column:
x - matrix(rnorm(10),nrow=5,ncol=2)
class(x) - foo
[-.foo - function(x, i, j, value) {
+ if(missing(i)) i - 1:nrow(x)
+
Try this:
x - matrix(rnorm(10),nrow=5,ncol=2)
class(x) - foo
[-.foo - function(x, i = TRUE, j = TRUE, ..., value) {
x - unclass(x)
x - NextMethod()
class(x) - foo
x
}
x[] - 100.0
