factorize {labdsv} | R Documentation |
Change Character Vectors in Data.frames to Factors
Description
Looks at each column in a data.frame, and converts character vector columns to factors.
Usage
factorize(df)
Arguments
df |
a data.frame |
Details
The function simply scans each column in a data.frame looking for character vector columns. For each character column it calls the ‘factor()’ function to convert the column to a factor.
Value
Returns a data.frame where every character column has been converted to a factor
Note
This function simplifies editing data.frames by allowing users to edit character columns (which have no levels constraints) and then converting the results to factors for modeling. It is often used in a cycle of
defactorize(df)
edit the columns as necessary to correct errors or simplify
factorize(df)
