Dear Dr. Lemon,
I am amazed, I did not know that a space could solve this issue. So you
mean that, besides being sensible to letter capitalization, R is also
sensible to spaces?
Many thanks!

Hi Jue,
The character sequence "<-" is preferentially interpreted as "assign the
value on the right to the name on the left". You can use parentheses to
force the unary minus to be interpreted:
if(a<(-1))
or you can just break the sequence with a space:
if(a< -1)
One less character, but
