| \title{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() |
| } |
| \details{ |
| Normally \R is run without looking at the value of \env{LC_NUMERIC}, |
| so the decimal point remains '\code{.}'. So the first three of these |
| components will only be useful if you have set the locale category |
| \code{LC_NUMERIC} using \code{Sys.setlocale} in the current \R session |
| (when \R may not work correctly). |
| |
| The monetary components will only be set to non-default values (see |
| the \sQuote{Examples} section) if the \code{LC_MONETARY} category is |
| set. It often is not set: set the examples for how to trigger setting it. |
| } |
| \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 \code{NULL}. |
| } |
| \seealso{ |
| \code{\link{Sys.setlocale}} for ways to set locales. |
| } |
| \examples{ |
| 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"). |
| \donttest{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)} |
| |
| \dontrun{read.table("foo", dec=Sys.localeconv()["decimal_point"])} |
