addInter: Add interactions

In nmm: Nonlinear Multivariate Models

Description

addInter add interactions into continuous equations.

Usage

addInter(eqcont, par_c, intv, inter_parl)

Arguments

eqcont	Vector of strings containing equations.
par_c	Names of coefficients.
intv	Vector of integers corresponding to coefficients to which interactions should be added.
inter_parl	Names of new coefficients (interactions).

Value

list: 1 - expressions of errors, equations, parameters to estimate

Examples

eq_c <- c("Tw ~ tw*w + ph1*Tc", "Tf1 ~ (1+w)^tw + ph1^3*Tc")
parl <- c("tw", "ph1")
intv <- c(1,0)
inter_parl <- c('yytw','yyph1')
res <- addInter(eq_c, parl, intv, inter_parl)
