File structure

The *.lrn file contains the input data as tab separated values. Features in columns, datasets in rows. The first column should be a unique integer key. The optional header contains descriptions of the columns.

Writing and Reading

DataIO.writeLRN — Function
writeLRN(filename::String, lrn::LRNData, directory=pwd())

Write the contents of a LRNData struct into a file.

DataIO.readLRN — Function
readLRN(filename::String, directory=pwd())

Read the contents of a *.lrn and return a LRNData struct.

Types and Constructors

DataIO.LRNData — Type
LRNData

LRNData represents the contents of a *.lrn file with the following fields:

  • data::Matrix{Float64}

    Matrix of data, cases in rows, variables in columns

  • column_types::Array{LRNCType, 1}

    Column types, see LRNCType

  • key::Array{Integer, 1}

    Unique key for each line

  • names::Array{String, 1}

    Column names

  • key_name::String

    Name for key column

  • comment::String

    Comments about the data

DataIO.LRNData — Method
LRNData(data::AbstractMatrix{Float64})

Convenience constructor for LRNData. Uses sensible defaults:

column_types=[9,1,1...]
key=[1,2,3...]
names=["C1","C2","C3"...]
key_name="Key"
comment=""
