I get the following error when I run qplot()
qplot(grade, read,data = hhm.long.m, geom = c("point", "smooth"))Error in smooth.construct.cr.smooth.spec(object, data, knots) : x has insufficient unique values to support 10 knots: reduce k.I am not sure how to tackle this problem. When I take a subsample (< 1000) than I am able to run that function but with my sample of ~ 40,000 qplot gives me that error. I have 6 grades.
Please cc me on reply. Thanks!
