Hi,
I am newbie to R so pardon me if this is not the forum for asking this
question.
I am getting the error "unexpected input in "evalq({" in the Boost Tutorial
example section 13.3 of Graham William's, "Data Mining with Rattle and R.
Below is the line as I have entered it and version information. (note: 2.14.2
is the latest version I can get to run on my MacBookPro)
What can I can I try other than other R versions to resolve this error?
> evalq({
data <- weather
nobs <- nrow(weather)
vars <- -grep('^(Date|Location|RISK_)', names(data))
form <- formula(RainTomorrow ~ .)
target <- all.vars(form)[1]
set.seed(42)
train <- sample(nobs, 0.7*nobs)
}, weatherDS)
Error: unexpected input in "evalq({"
