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...
