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.
Those weren't assignments. The arguments to ifelse() are named "test",
"yes", and "no".
You're right though that the expressions were messed up. Commas are
missing between arguments, and the parentheses don't appear to be in the
right place.
One suggestion for Kirsten: instead of
dat$cond == "cond1" | dat$cond == "cond2" |
dat$cond == "cond3" | dat$cond == "cond4"
it is shorter and a bit clearer to write
dat$cond %in% c("cond1", "cond2", "cond3", "cond4")
or maybe even
dat$cond %in% paste0("cond", 1:4)

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.
