This function inspects a data.table and attempts to identify columns that should be
numeric but have been read in as character, and changes types in-place.
This can happen when one or more fields contain non-numeric characters.
Usage
dt_set_autotypes(x, cols =NULL, verbosity =1L)
Arguments
x
data.table
cols
Character vector: columns to work on. If not defined, will work on all
columns
