Package 'atease'

S4-like syntax for accessing attributes of any object

Description

Package atease lets you write x@att as shorthand for attr( x, "att"), even for non-S4 objects. @<- is the analogue for replacements, called automatically during e.g. x@att <- 1. For an S4 object, @ and @<- access the slots, as usual; there might be some minuscule speed penalty, but (i) you shouldn't really be accessing slots of other people's S4 objects directly, and (ii) if you're writing your own S4 object, you won't be using the atease package! Although perfectly legal, this is no doubt considered all very naughty and would be reviled by S4 fans...

Usage

object@name
object@name<- value

Arguments

object	any object
name	the unquoted name of an attribute (or slot)
value	what to put in the attribute (or slot)

Examples

l <- list(0)
attr( l[[1]], 'thing') <- 66
l[[1]]@thing # 66
l[[1]]@thing <- 44
attr( l[[1]], 'thing') # 44
