I'm getting an error when trying to run the first model cell

Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) : 
  'x' must be atomic

I won't add this to the 0.1.1 release.

The formula setup code has an error. The double quotation marks in formula2 <- ... + residuals(... , model = "spde", ...) should be removed. So it should be residuals(... , model = spde, ...)
