R: Find Details of the Numerical Representations in the Current Locale

localeconv {base} | R Documentation

## Find Details of the Numerical Representations in the Current Locale

### Description

Get details of the numerical representations in the current locale.

### Usage

    Sys.localeconv()

### Value

A character vector with 18 named components. See your ISO C documentation for details of the meaning.
It is possible to compile R without support for locales, in which case the value will be `NULL`.

### See Also

`locales` for ways to set locales: by default R uses the C clocal for `"LC_NUMERIC"` and `"LC_MONETARY"`.

### Examples

    Sys.localeconv()
    ## The results in the default C locale are
    ##    decimal_point     thousands_sep          grouping   int_curr_symbol
    ##              "."                ""                ""                ""
    ##  currency_symbol mon_decimal_point mon_thousands_sep      mon_grouping
    ##               ""                ""                ""                ""
    ##    positive_sign     negative_sign   int_frac_digits       frac_digits
    ##               ""                ""             "127"             "127"
    ##    p_cs_precedes    p_sep_by_space     n_cs_precedes    n_sep_by_space
    ##            "127"             "127"             "127"             "127"
    ##      p_sign_posn       n_sign_posn
    ##            "127"             "127"

    ## Now try your default locale (which might be "C").
    old <- Sys.getlocale()
    Sys.setlocale(locale = "")
    Sys.localeconv()
    Sys.setlocale(locale = old)

    read.table("foo", dec=Sys.localeconv()["decimal_point"])
