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 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.
