In antonmalko/ibextor: Easy preprocessing of Ibex data

Description

A function to provide default names for columns and ensure that every column has a name

Usage

make_column_classes(n_cols, col_classes = NULL, partial_classes = TRUE)

Arguments

n_cols	numeric. Number of columns in the data
col_classes	character vector with classes to be assumed for the columns. Currently, the following classes are allowed: “character”, “numeric”, “integer”, “logical”, “factor”. Additionally, one may use “asis”, if the class of a column should not be changed. If the class for a column is not specified explicitly, “asis” will be assumed.
partial_classes	logical. If TRUE, the first seven columns will receive default classes: + subject - factor + md5_hash, controller, type, item - character (notice that in Ibex items can be identified with character strings, that's why item is not numeric by default), + presentation_order, element_number - numeric, So col_names will be taken to specify classes for columns starting from 8. If FALSE, col_classes will be taken as specifying classes for all columns. If there are less than 8 columns, partial classes will always be taken to be FALSE.

Value

vector with column classes
