[R] loess question

Hi All, I am trying to use loess to smooth a 2D image, and also obtain the standard error for every pixel. I see that the standard error does not make sense. For example, running the following: library(stats) x <- array(c(1:100), dim=c(100,100)) y <- t(x) v <- exp(-((x-50)^2+(y-50)^2)/30^2)

Hi, suppose I have a vector of values in 'A'. Suppose I use: scatter.smooth(A) to add in a smooth curve. Is there a way to obtain the maximum value of the smoothed curve? Anyways, any help will be greatly appreciated! -- View this message in context: http://www.nabble.com/Loess-question-tp247385
