Warning Messages

Usage

warning(message)

Description

warning generates a warning message that corresponds to its argument. The result depends on the value of options("warn"). If warn is negative warnings are ignored; if it is zero they are stored and printed after the top–level function has completed; if it is one they are printed as they occur and if it is 2 (or larger) warnings are turned into errors. If warn is zero a top–level variable last.warning is created. It contains the warnings which can be printed via a call to warnings.

Examples



if(eigenval < 1.e-7) warning("system near singular")

if(eigenval < 1.e-7) warning("system near singular")
