[R] inconsistent behaviour of ifelse and if ... else

[Joerg van den Hoff]

is the behaviour

val <- ifelse(TRUE, numeric(0), 123)
val  #NA

intended or is it a bug, i.e. should an empty object be returned as 
might be expected(also in comparsion to what an explicit
val <- {if(TRUE) numeric(0) else 123} yields)?

thanks,

joerg
