Gist demonstrating an R error
# The question: why does make.plot.1 cause an error?
# make.plot.2 and make.plot.3 work ok.
#
# I'm trying to use ggplot to make a scatter plot with
# with size mapped to the "s" variable in the dataframe.
# When I try to draw circles on top of the scatter plot using geom_path, I get
# errors.
# The plot works if I choose to not map size or not to draw the circles.

Predict.lm not working for matrix data
# Make a dataset where Y is cubic in X, plus noise:
n <- 1000
x <- runif(n)
x <- sort(x)
eps <- rnorm(n)
beta <- c(1, 2, 3)
X <- poly(x, 3, raw = TRUE)
y <- X %*% beta + eps
# Fit the data
