A wrapper for strsplit. Divides a column into multiple columns by dividing the contents

  ...
)

column_name

(character) The column name in the annotation_source split.

separator

Inheritance

A split_column object inherits the following struct classes:

[split_column] -> [model] -> [struct_class]

Examples

M <- split_column(
        column_name = "V1",
        separator = "_",
        clean = FALSE,
        padding = FALSE,
        keep_indices = numeric(0))
