R help - Nov 2000 - Real data type in FORTRAN

Dear all,

In FORTRAN we specify real*4 data type,
what is the equivalence of this data type
in R? is it single?

Perhaps you do, but the ISO Standard specifies REAL. What that
maps to is system-specific.

See ?Foreign.  R does not have a `single' data type, but .Fortran
can convert a double data type with the right attribute to and from 
a Fortran REAL.
