SEXP() ATTRIB ( SEXP x )

Get the attributes of an R value.

Parameters:

Parameters:

symbol	the SYMSXP that should be looked up
rho	an ENVSXP that is the starting point for the lookup

Returns:: Returns the binding value, or R_UnboundValue if none was found.

Can cause GC:: if one of the environments is of class "UserDefinedDatabase" or active bindings (R_MakeActiveBinding) are used.

	)

Find the binding for a symbol in a single environment.

The lookup will query user defined databases if the environment is of class "UserDefinedDatabase" (using R_ObjectTable), and query active binding (R_MakeActiveBinding).

Parameters:

rho	an ENVSXP in which the lookup will take place
symbol	the SYMSXP that should be looked up
doGet	specifies if the lookup is done to get the value (TRUE), as opposed to only determining whether there is a binding. The only effect is that, if this is FALSE, R_ObjectTable::exists is called before calling R_ObjectTable::get.

Returns:: Returns the binding value, or R_UnboundValue if none was found.

Can cause GC:: if the environments is of class "UserDefinedDatabase" or active bindings (R_MakeActiveBinding) are used.
