miscellaneous mathematical functions on RObjects -- miscellaneous mathematical functions on R objects
When passed an RObject, abs and sqrt do the expected thing, calling the corresponding R functions to compute the absolute value and square root of the given input, respectively.
i1 : x = RObject(-2)
o1 = [1] -2
o1 : RObject of type integer
i2 : abs x
o2 = [1] 2
o2 : RObject of type integer
i3 : sqrt oo
o3 = [1] 1.414214
o3 : RObject of type double
