I was using the lines.polynomial method for plotting piecewise polynomials
(parts of splines). I needed a feature to limit the range of plotting using a
parameter given to the function (as opposed to par("usr")). I think that the
following changes would be a nice addition:
lines.polynomial <- function (x, len = 100, xlim=par("usr")[1:2],
ylim=par("usr")[3:4],...)
{
p <- x
x <- seq(xlim[1], xlim[2], len = len)
y <- predict(p, x)
y[y <= ylim[1] | y >= ylim[2]] <- NA
lines(x, y, ...)
}
