discretize
discretizes data
using the equal frequencies or equal width binning algorithm.
discretize( data,disc="equalfreq",nbins=sqrt(nrow(data)) )
data |
A data.frame containing data to be discretized. The columns contains variables and the rows samples. |
disc |
The name of the discretization method to be used :"equalfreq" or "equalwidth" (default : "equalfreq") - see references. |
nbins |
Integer specifying the number of bins to be used for the discretization. By default the number of bins is set to sqrt(N) where N is the number of samples. |
discretize
returns the discretized dataset.
