Hi: Try this: library('lattice') xyplot(y ~ x, type = c('g', 'p'), panel = function(x, y, ...){ panel.xyplot(x, y, ...) panel.lines(x, predict(fm), col = 'black', lwd = 2) } ) HTH, Dennis On Wed, Nov 23, 2011 at 9:18

[R] lines and points in xyplot()

2011-11-23 Thread Doran, Harold
Given the following data, I want a scatterplot with the data points and the predictions from the regression. Sigma <- matrix(c(1,.6,1,.6), 2) mu <- c(0,0) dat <- mvrnorm(5000, mu, Sigma) x <- dat[,1] * 50 + 200 y <- dat[,2] * 50 + 200 fm <- lm(y ~ x) ### This gives the regression line, but not
