as.kernelMatrix | R Documentation |
as.kernelMatrix
in package kernlab can be used
to coerce the kernelMatrix class to matrix objects representing a
kernel matrix. These matrices can then be used with the kernelMatrix
interfaces which most of the functions in kernlab support.

## Create toy data x <- rbind(matrix(rnorm(10),,2),matrix(rnorm(10,mean=3),,2)) y <- matrix(c(rep(1,5),rep(-1,5))) ### Use as.kernelMatrix to label the cov. matrix as a kernel matrix ### which is eq. to using a linear kernel K <- as.kernelMatrix(crossprod(t(x))) K svp2 <- ksvm(K, y, type="C-svc") svp2
