Hello, I have what should be an easy question. I'm a new r user and making the transition from menus to the command line so as to do batch processing of tons of data. One of my data streams needs to be detrended. It's a vector of numbers that follows a negative exponential decay. I need to fit a curve to it and use the residuals as an object. The data looks something like this:
foo.dat <- (0.83 * exp(-0.017 * 1:1000) + 0.5) + rnorm(1000,0,0.05) plot(foo.dat, type = "l") That is an example the parameters for foo.dat change slightly. So, I need to fit a neg exponential curve to that type of data without specifying the parameters beforehand and save the residuals as an object. It will have to accomadate being in a loop. How can I do this? Regards, CG ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
