\begin{Description}\relax
Get details of the numerical representations in the current locale.\end{Description}
\begin{Usage}
\begin{verbatim}
Sys.localeconv()
\end{verbatim}
\end{Usage}
\begin{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}.\end{Value}
\begin{SeeAlso}\relax
\code{\Link{locales}} for ways to set locales: by default \R{} uses the
C clocal for \code{"LC\_NUMERIC"} and \code{"LC\_MONETARY"}.\end{SeeAlso}
\begin{Examples}
\begin{ExampleCode}
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"])
