Sys.localeconv: Find Details of the Numerical and Monetary Representations in the Current Locale

Description

Get details of the numerical and monetary representations in the current locale.

Usage

Sys.localeconv()

Arguments

Value

A character vector with 18 named components. See your ISO C documentation for details of the meaning.
It is possible to compile Rwithout support for locales, in which case the value will be NULL.

Details

Normally Ris run without looking at the value of LC_NUMERIC, so the decimal point remains '.'. So the first three of these components will only be useful if you have set the locale category LC_NUMERIC using Sys.setlocale in the current Rsession (when Rmay not work correctly).

The monetary components will only be set to non-default values (see the Examples section if the LC_MONETARY category is set. It often is not set: set the examples for how to trigger setting it.

Examples

Run this code

Sys.localeconv()
## The results in the 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()
## The category may not be set:
## the following may do so, but it might not be supported.
Sys.setlocale("LC_MONETARY", locale = "")
Sys.localeconv()
## or set an appropriate value yourself, e.g.
Sys.setlocale("LC_MONETARY", "de_AT")
Sys.localeconv()
Sys.setlocale(locale = old)

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