Hi, I have a question regarding the usage of prediction in R: I have an input data set X, and an output data set Y, I can build up the correlation between them using kcca() of kernlab, but after I have that correlation, how can I predict the output Y1 of a new input X1? I read about the gausspr() but I don't know how to bring the result of kcca() to use as parameters for gausspr(). Any replies is appreciated! Thanks a lot, James. -- View this message in context: http://r.789695.n4.nabble.com/How-to-use-prediction-tp2527030p2527030.html Sent from the R help mailing list archive at Nabble.com.
