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

From: Joerg van den Hoff <j.van_den_Hoff_at_fz-rossendorf.de>

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)?
