Examples

## Not run: 
## Estimating MSE for 3 variants of both
## regression trees and SVMs, on  two data sets, using one repetition
## of 10-fold CV
library(e1071)
library(DMwR)
data(swiss)
data(mtcars)

## running the estimation experiment
res <- performanceEstimation(
  c(PredTask(Infant.Mortality ~ .,swiss),PredTask(mpg ~ ., mtcars)),
  c(workflowVariants(learner="svm",
                     learner.pars=list(cost=c(1,10),gamma=c(0.01,0.5))),
    workflowVariants(learner="rpartXse",
                     learner.pars=list(se=c(0,0.5,1)))
  ),
  EstimationTask("mse")
  )

## the names of the metrics that were estimated in the above experiment
taskNames(res)
