class() on substitute(...) output?
Does it make sense to talk about the class of the output of
substitute(...)? I'm puzzled by the following outputs:
ee <- list(
A = substitute( a <- 1 ),
B = substitute({ a <- 1 }),
C = substitute(( a <- 1 )),
D = substitute( a == 1 )
)
> t(sapply(ee, FUN=function(e) { c(typeof=typeof(e), mode=mode(e), class=class(e)) }))
typeof mode class
A
