Convert columns into numeric — convert_to

When the 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.

Usage

convert_to_numeric(data, target_columns = NULL, lang = c("en", "fr", "es"))

Arguments

data: The input data frame or linelist
target_columns: A vector of the target column names. When the input data is a linelist object, this parameter can be set to linelist_tags if the tagged columns are those to be converted into numeric.
lang: The text's language. Currently one of "en", "fr", "es".

Value

A data frame wherein all the specified or detected columns have been transformed into numeric format after the conversion process.

Examples

dat <- convert_to_numeric(
  data = readRDS(
    system.file("extdata", "messy_data.RDS", package = "cleanepi")
  ),
  target_columns = "age",
  lang = "en"
)
