When this function is invoked without specifying the column names to be
converted, the target columns are the ones returned by the scan_data()
function. Furthermore, it identifies columns where the proportion of numeric
values is at least twice the percentage of character values and performs the
conversion in them. The function internally makes call of the main function
from the numberize package.
Usage
convert_to_numeric(data, target_columns = NULL, lang = c("en", "fr", "es"))Arguments

A

Value
