In bentyeh/r_bentyeh: Personal Scripts

Description

Convert an array to a data frame.

Usage

arrayToDf(ar)

Arguments

ar

An array.

Value

data.frame. dim = c(prod(dim(ar)), length(dim(ar)) + 1).

• Rows: One row per element of the array. Rows are "entered" into the data frame in column major order.

• Columns: One column per dimension of the array, plus one column for the values in the array.

  • Column names are retained from names of array dimensions (names(dimnames(ar)). Where non-existant, column names are given as "d#", where # is the index of the dimension.

  • For each column, if the corresponding array dimension was named, then the column is of class character. Otherwise, the column is of class numeric.

  • The last column (the values from the array) is named "value".
