So my friend is in a stats class, and his professor keeps giving him faulty code.
He's supposed to type in:
plot(brainwt ~ headsize, data = brainhead[brainhead$gender == "male",], pch = 1, col = "blue", main = "Brain Weight versus Head Size by sex”, xlab = "head size (cm^3)", ylab = "brain weight (grams)" xlim = c(2700,5000) ylim = c(950,1700)
But he gets this error:
Error: unexpected symbol in:
" main = "Brain Weight versus Head Size by sex”,
xlab = "head"
We've tried messing around with placements of commas, quotations, so on, nothing fixes it. Any help?
