Partial evaluation of a 'ratioOfQsprays' fraction of polynomials

Description

Substitute some values to a subset of the variables of a ratioOfQsprays fraction of polynomials.

Usage

substituteRatioOfQsprays(roq, values)

Arguments

`roq`	a `ratioOfQsprays` object
`values`	the values to be substituted; this must be a vector whose length equals the number of variables of `roq`, and whose each entry is either `NA` for non-substitution or a "scalar" `x` such that `as.character(x)` is a quoted integer or a quoted fraction, e.g. a `bigq` number

Value

A ratioOfQsprays object.

Examples

library(ratioOfQsprays)
x <- qlone(1)
y <- qlone(2)
z <- qlone(3)
roq <- (x^2 + y^2 + x*y*z - 1) / (x + 1)
substituteRatioOfQsprays(roq, c("2", NA, "3/2"))
