[R] nlme formula from model specification

Dear R-community, I'm analysing some noise using the nlme-package. I'm writing in order to get my usage of lme verified. In practise, a number of samples have been processed by a machine measuring the same signal at four different channels. I want to model the noise. I have taken the noise (the s

[R] e1071: Cannot predict probabilities

Dear list. I using the SVM-methods from the e1071, but I can't get the probabilities when predicting. Code: x <- matrix(rbinom(100, 10, 0.3), ncol=2) y <- apply(x, 1, sum) fit <- svm(y ~ x, method = "C-classification", kernel = "radial", probability = TRUE) predict(fit, x, probability=TRUE) Here
