Retapes an existing CppAD tape but with some of original dynamic parameters fixed to specified values. For creating this tape, the values of pfun$xtape is used.

Usage

fixdynamic(pfun, theta, isfixed)

Arguments

pfun	An Rcpp_ADFun object.
theta	A numerical vector specifying the value of all dynamic parameters of pfun. Some of these will be fixed according to isfixed, the remainder will remain dynamic.
isfixed	A boolean vector same length as theta. TRUE values are fixed at the value of theta, FALSE values are left dynamic.

Value

An Rcpp_ADFun object.
