chr_numeric: Charcter to numeric conversion

In antaldaniel/surveyreader: Data cleaning and integration for survey files

Description

Convert a character to a numeric expression.

Usage

chr_numeric(column, validate_min = NA, validate_max = NA, digits = NA,
  decimals = "point", na_id = "NA", is_integer = FALSE)

Arguments

column	A column from a survey data frame where gender is recorded.
validate_min	The valid minimum value. Defaults to NA in which case no validation takes place.
validate_max	The valid maximum value. Defaults to NA in which case no validation takes place.
digits	How many digits are valid in the raw date. Defaults to NA when digits are not truncated. 2 uses only the first two characters of the raw data. Digits are counted as characters. So keeping 1.5 requires digit = 3.
decimals	Defaults to "point", alternative is "comma"
na_id	Is there a special character ID for missing variables? (Default: "NA" )
is_integer	Numeric or integer should be returned? Defaults to FALSE in which case no validation takes place. If you get a warning with NA conversion, you are likely to have several NA characters, such as missing and NA at the same time.

Examples

chr_numeric(column = as.character (c(1982, 1990.5, 2019,
                                     "missing", NA, 1678)),
            validate_min  = 1900, validate_max = 2017,
            digits = NA, decimals = "point",
            na_id = "missing",
            is_integer = FALSE )
chr_numeric(column = as.character (c("1 - egyet", "11 - tizenegyet",
            "missing", "2")),
            validate_min  = NA, validate_max = NA,
            digits = 2,
            na_id = "missing",
            is_integer = FALSE )
