RObject - RObject -- subtract R objects

Description

Subtract two R objects.

i1 : x = RObject 5

o1 = [1] 5

o1 : RObject of type integer

i2 : y = RObject 2

o2 = [1] 2

o2 : RObject of type integer

i3 : x - y

o3 = [1] 3

o3 : RObject of type integer

It may also be used as a unary operator.

i4 : -x

o4 = [1] -5

o4 : RObject of type integer

One of the operands may be a Macaulay2 object. It will be converted to an RObject before the operation is performed.

i5 : x - 2

o5 = [1] 3

o5 : RObject of type integer

i6 : 5 - y

o6 = [1] 3

o6 : RObject of type integer
