[R] Ifelse statements and combining columns

Not a reproducible example, so a bit of guessing here, but

a) don't try to assign results to variables inside the ifelse. That is,  remove all the single-equals signs and "test" variables. If you really need to conditionally assign variables then use "if"... but chances are good you don't need that. 

b) "closure" is effectively another word for"function"... functions like cbind are called with argument lists delimited by parentheses, not brackets, and having a missing argument to the cbind function will be of no use.
