combinat::warnDeprecated – issue of warnings when deprecated features are used

combinat::warnDeprecated controls whether deprecated functions issue warnings.

Calls:

combinat::warnDeprecated()

combinat::warnDeprecated(mode)

Parameters:

Return Value:

the (former) setting of the switch

Details:

• The combinat library in MuPAD 2.5 is a major rewrite compared to MuPAD 2.0. Several functions or features known from earlier versions are considered deprecated and only forward calls to the corresponding new functions. After combinat::warnDeprecated(TRUE) is invoked, each such call will issue a warning.

• combinat::warnDeprecated(TRUE) turns on those warnings, combinat::warnDeprecated(FALSE) switches them off, and combinat::warnDeprecated() returns the current setting.

• The warnings are turned on by default when the MuPAD-Combinat package is explicitly loaded by the user and off otherwise.
