Get details of the numerical and monetary representations in the current locale.
Sys.localeconv()
These settings are usually controlled by the environment variables LC_NUMERIC and LC_MONETARY and if not set the values of LC_ALL or LANG.
Normally R is run without looking at the value of LC_NUMERIC,
so the decimal point remains '.
'. So the first three of these
values will not be useful unless you have set LC_NUMERIC in
the current R session.
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
.
Sys.setlocale
for ways to set locales.
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").
