The error occurs when the "effect' function runs.
# Effects Plot ===== 
  print(plot(effect("net:magType",
    netBymagType),
    main = paste("Effect Plot - net by magType\n", Sys.Date()),
    lwd = 2,
    cex = 1.1,
    color = "black",
    ylab = "Maginitude",
    xlab = paste("'net' = Source of the Information \n",
      "magType = The Method used to Calculate the Magnitude")))

Error in rk.record.plot$.save.tlo.in.hP() : 
  could not find function "trellis.last.object"

Thanks for reporting. I'll try to look into this, soon, but very distracted, ATM.

Could you add the output of
    getAnywhere ("trellis.last.object")
to this report (after the error)?

For the time being, you should be able to work around this by disabling the plot history feature, either for this call, only (rk.without.plot.history()) or entirely (Settings->Onscreen Graphics->Screen device history).

Error in { :
   task 1 failed - "could not find function "trellis.last.object""
 > getAnywhere("trellis.last.object")
A single object matching ‘trellis.last.object’ was found
It was found in the following places
   namespace:lattice
with value

function (..., prefix = lattice.getStatus("current.prefix"))
{
     if (!lattice.getStatus("current.plot.saved", prefix = prefix)) {
         warning("Requested 'trellis' object was not saved")
         return(invisible(NULL))
     }
     ans <- lattice.getStatus("last.object", prefix = prefix)
     update(ans, ...)
}
<environment: namespace:lattice>

Thank You.

Hi!

Sorry for the long delay. I'm having trouble running your example, but I think I have an idea what's going wrong.

Can you confirm that the problem goes away, if you properly attach the lattice package (instead of just loading the namespace):
  library(lattice)

?

In a separate session, can you confirm that running the following fixes the issue?

assign (".save.tlo.in.hP", function (devId = dev.cur()) 
{
    if (!.is.device.managed(devId)) 
        return(invisible())
    devId <- as.character(devId)
    histPositions[[devId]]$plot <<- lattice:::trellis.last.object()
    histPositions[[devId]]$tlo.ls <<- get("lattice.status", envir = lattice:::.LatticeEnv)
    invisible()
}, envir=rk.record.plot
)

Regards
Thomas

Committed on 04/06/2017 at 19:00.
Pushed by tfry into branch 'frameworks'.

Fix breakage with trellis plots, when lattice is imported as a namespace, only, not on the search path.
