paramCoreIO(model, fileName, io=c("read","write")) 

Arguments

model

The model structure as returned by CoreModel.

fileName

Name of the parameter file.

io

Controls weather the parameters will be read or written.

Examples

# use iris data
# build random forests model with certain parameters
modelRF <- CoreModel(Species ~ ., iris, model="rf", 
              selectionEstimator="MDL",minNodeWeightRF=5,
              rfNoTrees=50, maxThreads=1)

# writes all the used parameters to file
paramCoreIO(modelRF, "parameters.par", io="write")
# and reads them back into the model
paramCoreIO(modelRF, "parameters.par", io="read")

# clean up for the sake of R package checks
file.remove("parameters.par")

destroyModels(modelRF) # clean up
