newDeriv R Documentation
newDeriv
Description
Define a new derivative expression.
Usage
newDeriv (expr, deriv, derivEnv = sysDerivs)
Arguments
expr
An expression represented as a quoted expression.
deriv
The derivative. See Details below.
derivEnv
The environment in which to store the setting.
Details
Both expr and deriv are treated
as unevaluated expressions.
deriv should include the sum of derivatives with respect to
all variables similar to a “total derivative” using
D for the differential. See the examples
below.
This is mainly intended for internal use.
Examples
newDeriv(sin(x), cos(x)*D(x))
newDeriv(x*y, x*D(y) + D(x)*y)
nlsDeriv(quote(sin(x)*sin(y)), "x")
