I highly recommend making friends with the str function. Try
str( 1 )
str( 1:2 )
Interesting. But to me counter-intuitive. Since R makes no distinction
between scalars and vectors of length 1 (or more accurately I think,
since in R there is *no such thing as a scalar*, only a vector of length
1) I don't see why "1" should be treated in a manner that is
categorically different from the way in which "1:2" is treated.
Can you, or someone else with deep insight into R and its rationale,
explain the basis for this difference in treatment?
for the clue you need, and then
sapply( 1:2, identical, 1L )
cheers,
