convert_to_numeric: Convert columns into numeric

Description

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"))

Value

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

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 to apply the conversion exclusively to the tagged columns. .

lang

A <character> with the text's language. Currently one of "en", "fr", "es".

Examples

data <- readRDS(
  system.file("extdata", "messy_data.RDS", package = "cleanepi")
)

# convert the 'age' column into numeric
dat <- convert_to_numeric(
  data = data,
  target_columns = "age",
  lang = "en"
)

# print the report from this operation
print_report(data = dat, "converted_into_numeric")
