Parameters injected into a solve by a par-loader hook

Returns the parameters (e.g. trained neural-network weights) that a registered par-loader wrote into the solve parameter vector, saved on the solved object so re-solving from it restores them.

Usage

rxInjectedPars(obj)

Arguments

obj

a solved rxode2 object.

Value

a named numeric vector, or NULL if nothing was injected.

Examples

# \donttest{
f <- function() {
  ini({
    tcl <- -2
  })
  model({
    cl <- exp(tcl) * WT
    d/dt(depot) <- -cl * depot
  })
}
u <- rxode2(f)

#> ℹ parameter labels from comments are typically ignored in non-interactive mode
#> ℹ Need to run with the source intact to parse comments
rxForcedPars(u) <- c(WT = 2)
rxForcedPars(u)
#> WT

ev <- et(amt = 100) |> et(1:8)
ev$WT <- 1
# the forced WT = 2 overrides the data WT = 1
