animation function lookup doesn't work when ndtv not loaded

[skyebend]

User Deisy Gysi reports when the package is namespace attached but not loaded, compute.animation isn't able to locate the the internal network.layout.animate.* functions

This would be great to fix so that packages dependent on this could be CRAN ready. Current solution/hack I have used on my fork is to create a new argument for compute.animation that allows the layout.fun to be specified explicitly overriding the function match:

 if(!is.null(force.layout)){
  layout.fun <- force.layout
  } else {
  layout.fun <- try(match.fun(paste("network.layout.animate.", animation.mode, sep = "")), silent = TRUE)
  if (class(layout.fun) == "try-error"){
      stop(paste("Error in compute.animation: no network animation layout function for animation.mode ", animation.mode))
  }
  }

fixing this will require a bit of refactoring in how ndtv looks up and locates user-added layout functions. As a work around, have you tried just adding Depends ndtv in the namespace to force ndtv to be loaded?

I have just tried depends and it builds and passes CRAN.

I am having a similar issue. ndtv is already listed as "Depends" in my DESCRIPTION file but I still get the error:
Error in compute.animation(dynamicWA, animation.mode = "kamadakawai", : Error in compute.animation: no network animation layout function for animation.mode
