check_nonnum: Check elements that are not numeric

Description

Finds the elements that cannot be converted to numeric in a character vector. Useful when setting the strategy to clean numeric values.

Usage

check_nonnum(
  x,
  return_idx = FALSE,
  show_unique = TRUE,
  max_count = NULL,
  random_sample = FALSE,
  fix_len = FALSE
)

Value

The (unique) elements that cannot be converted to numeric, and their indexes if return_idx is TRUE.

Arguments

x

A string vector that stores numerical values.

return_idx

A logical value. If TRUE, return the index of the elements that are not numeric.

show_unique

A logical value. If TRUE, return the unique elements that are not numeric. Omitted if return_idx is TRUE.

max_count

An integer. The maximum number of elements to show. If NULL or 0, show all elements. Omitted if return_idx is TRUE.

random_sample

A logical value. If TRUE, randomly sample the elements to show. Only works if max_count is not NULL or 0.

fix_len

A logical value. If TRUE, fill the vector with NA to fix the length to max_count.

Details

The function uses the as.numeric() function to try to convert the elements to numeric. If the conversion fails, the element is considered non-numeric.

Examples
