OK, this should be trivial but I'm not finding it. I want to compress the
test,
if (i==7 | i==10 | i==30 | i==50) {}
into something like
if (i in c(7,10,30,50)) {}
so I can build a "excludes" vector
excludes <- c(7,10,30,50)
and test
if (i in excludes) {}
However, I'm not finding a clue on how to accomplish this, if it can be
done. Would someone with more R experience lend a helping hand please? A
reference (so I can continue learning) would also be appreciated.
Thanks...
