DSEflags {dse1} | R Documentation |
Determines if compiled code should be used or not.
.DSEflags(new)
new |
A list which must have elements COMPILED and DUP. |
Setting flags with this function is primarily for debugging. It should not
normally be needed by users. If called with not arguments,
.DSEflags()
returns the current setting.
Several dse functions which call compiled fortran or C code will use
the equivalent S/R version if the .DSEflags()$COMPILED
returns
FALSE
. .DSEflags()$DUP
is passed to
fortran calls and controls whether R duplicates arguments passed
to the fortran code. The safe setting is TRUE
. Setting FALSE
saves some memory but does not seem to give much speed gain.
The flag settings affect whether and how compiled fortran or C code is called.
