Description

Determines if compiled code should be used or not.

DSE

Details

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.

Examples

.DSEflags(list(COMPILED=TRUE, DUP=TRUE))
    .DSEflags()$COMPILED
