Re: [R] Unable to run smoother in qplot() or ggplot() - complains about knots

I am guessing his data is at fixed time points or something similar. As a "cheat" you can apply a jitter function to the x values and it should draw... g <- ggplot(data, aes(x = jitter(x), y = y,... J -- View this message in context: http://r.789695.n4.nabble.com/Unable-to-run-smoother-in-qplo

[R] Unable to run smoother in qplot() or ggplot() - complains about knots

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
