Mathematical operations
Description
This generic provides a common dispatch mechanism for all regular unary
mathematical functions. It is used as a common wrapper around many of the
Summary group generics, the Math group generics, and a handful of other
mathematical functions like mean() (but not var() or sd()).
Usage
vec_math(.fn, .x, ...)
vec_math_base(.fn, .x, ...)
Arguments
.fn |
A mathematical function from the base package, as a string. |
.x |
A vector. |
... |
Additional arguments passed to |
Details
vec_math_base() is provided as a convenience for writing methods. It
calls the base .fn on the underlying vec_data().
Included functions
From the Summary group generic:
prod(),sum(),any(),all().From the Math group generic:
abs(),sign(),sqrt(),ceiling(),floor(),trunc(),cummax(),cummin(),cumprod(),cumsum(),log(),log10(),log2(),log1p(),acos(),acosh(),asin(),asinh(),atan(),atanh(),exp(),expm1(),cos(),cosh(),cospi(),sin(),sinh(),sinpi(),tan(),tanh(),tanpi(),gamma(),lgamma(),digamma(),trigamma().Additional generics:
mean(),is.nan(),is.finite(),is.infinite().
Note that median() is currently not implemented, and sd() and
var() are currently not generic and so do not support custom
classes.

vec_arith() for the equivalent for the arithmetic infix operators.
