Hi,
is there a way to define a method say '$$' that would behave like '$'
and allow calls like 'a$$name'?
Thanks.
Renaud
No. This is not grammatically valid syntax:
> parse( text = 'a$$name' )
Erreur dans parse(text = "a$$name") : '$' inattendu(e) dans "a$$"
But you can define custom methods for $.
setClass( "Foo", representation( n = "integer" ) )
setMethod( "$", "Foo", function(x, name ){
function( ) rnorm( x...@n )
} )
foo <- new( "Foo", n = 10L )
foo$bla( )
