Examples

## Not run: 
  # requires the qs package to read an older nlmixr2 v3 fit (qs is no
  # longer on CRAN); regenerates the rxode2 model so it works again
  # fit <- readRDS(system.file("testfit_nlmixr3.rds", package = "nlmixr2est"))
  # fit <- try(nlmixr2fix(fit))
  # if (!inherits(fit, "try-error")) rxSolve(fit)

## End(Not run)
