fail to read waic

[Qing Zhao]

Dear group,

I ran this model and calculated the WAIC value. When I read in the saved output file (in .RData format), everything is fine. However, when I copied the output to another computer, I only got this when I tried to read the WAIC value:

> fit$WAIC
An object of class "waicNimbleList"
<S4 Type Object>
attr(,".xData")
<environment: 0x000002746e532500>

The samples can be correctly read. This is probably not a big problem since I can always use the original computer, but I'm just curious why this happens and how it can be solved. Thank you.

Best,

Qing

Dear Qing,

Thanks for posting the question. Unfortunately, nimbleList objects cannot be successfully saved and loaded because they access data residing in C++ objects. You would need to copy fields from the waicNimbleList into regular R objects to save them.
