Hi everyone,
I'm having some trouble with my ifelse statements.
I'm trying to put 12 conditions within 3 groups. Here is the code I have so
far:
dat$cond <- ifelse(test = dat$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" )
I keep getting an error statement about an invalid ). I've tried several
permutations to fix, but without luck.
Also, can anyone help me bind columns together? I've tried:
cbind[, c(15:25)] but get the error: object of type 'closure' is not
subsettable
Thank you in advance!

Hello,
Your ifelse statement is a mess. I cannot make sense of it. Let me try
to explain where I've lost it.
dat$cond <- ifelse(test = dat$cond == "cond1"
This is already very bad, do you mean dat$cond == "cond1" ?
Maybe you mean that condition OR the others below, but then there's one
'|' missing, just before the last condition.
| dat$cond == "cond2" |
dat$cond == "cond3" dat$cond == "cond4"
After this your code should have a comma. It's missing.
Maybe you can tell us in plain english the conditions your ifelse should
process.
Hope this helps,
Rui Barradas

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. -- Sent from my phone.

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.

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) Duncan Murdoch> 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. >
Hi I may be completely wrong, but if your data was factor you could easily change its levels without any ifelse stuff.
