search for: dens1

Hi all. I would like to highlight overlapping regions of two densities and I could not find a way to do it. Here is the sample code: myd <- c(2,4,5, 4,3,2,2,3,3,3,2,3,3,4,2,4,3,3,3,2,2.5, 2, 3,3, 2.3, 3, 3, 2, 3) myd1 <- myd-2 plot(range(density(myd)$x, density(myd1)$x), range(density(myd)$y, density(myd1)$y), type = "n") lines(density(myd), col=1, lwd=4)

Hi all, this is OT, but maybe someone can give me a clue. I've got data from eye tracker experiments (750 data points). These figures show how the data lock like |** * ***** |*** ****** | ** **** | * * | | * * | | * |-------------- |--------------- Y axes display velocity, x axes display time, * are the data points.

Are there any functions in R for fitting distributions? In particular, I would like to fit the weibull and extreme-value distributions when: i) the data are given and the maximum likelihood estimates are required; ii) the sample moments are available but the complete data record is not (so moment estimates are required). Any suggestions will be gratefully received.

An object of class `density' has `x' and `y' components, which are what you need to do the plot. Just bind them into a matrix and use write() to write to a file.
