[R] Ifelse statements and combining columns

That ifelse statement is a mess, it is missing brackets, comma separators
between arguments and & or | between conditions. The bracket error points
towards the invalid bracket you had in the second ifelse since it expects
and yes and a no argument alongside conditions.
ifelse(test = (dat$cond == "cond1" | dat$cond == "cond2" | dat$cond ==
"cond3" | dat$cond == "cond4"),yes = "Uniform" , no =
ifelse(test = (dat$cond == "cond5" | dat$cond =="cond6" | dat$cond ==
"cond7" | dat$cond == "cond8"), yes = "Biased Low" ,no = "Biased High"))
This should be what you want.
cbind is a function, therefor it is not subsettable.
if you are passing 2 arguments to cbind then cbind takes the form
cbind(c(1:n),c(1:n)) and constructs a matrix of dimension 2 x n. For
unequal vectors the shorter vector will be recycled.
