Hi list members,
?"else" tells us
In particular, you should not have a newline between '}' and
'else' to avoid a syntax error in entering a 'if ... else'
construct at the keyboard or via 'source'.
but there's no syntax error when you break the line between "}" and
"else" in a function, e.g.
f = function(x) {
if (x) {
1
} # a new line here!
else {
2
}
}
> f(TRUE)
[1] 1
> f(FALSE)
[1] 2
Seems strange...
Regards,
Yihui
