I created a type of object similar to a data frame. In some circumstances, It
needs special methods for [ and [- and rbind() (but not cbind()). Then I
found this in the cbind()/rbind() man page:
The method dispatching is _not_ done via 'UseMethod()', but by
C-internal dispatching.
Hum. Then, I need to be more accurate. My object is of class
c(bar, data.frame). So, by virtue of ...
The dispatch algorithm is described in the source file
('.../src/main/bind.c') as
1. For each argument we get the list of possible class
memberships from the class
Actually you can add your own method. See
library(zoo)
rbind.zoo
for an example.

Maybe you could use rbind2, which has an S4 generic in the methods
package, instead?
# BOD is a data frame built into R
foo - structure(BOD, class = c(bar, data.frame))
setOldClass(bar)
setMethod(rbind2, signature(x = bar, y = bar),
function(x, y) {
cat(Hello!\n)
