Hello,
I wonder if this will make it through the spam filters given the
subject line.
I'm seeing the following when trying to call a dollar method inside of
a dollar method.
setClass("Foo", representation(d="list"))
[1] "Foo"
f <- new("Foo", d=list(bob=1, alice=2))
## We can call dollar at this level and it works as expected
`$`(f, "bo")
[1] 1
`$`(f, "al")
[1] 2
## So set a method on Foo that does this
setMethod("$", "Foo", function(x, name) `$`([EMAIL PROTECTED], name))
[1] "$"
## But it doesn't work. Why?
f$bo
NULL
f$al
NULL
## Here is a hackish workaround.
setMethod("$", "Foo", function(x, name)
eval(substitute([EMAIL PROTECTED], list(FOO=name))))
[1] "$"
f$bo
[1] 1
f$al
[1] 2
Other suggestions for workarounds? Is this a bug?
+ seth
