error in isotope-guided-walk.R: the object d18o_world on line 123 wasn't found

Excellent question received by email: running isotope-guided-walk.R leads to an error on line 123:

Error in calRaster(known = d, isoscape = d18o_world) : 
  object 'd18o_world' not found

Update pending and commit to follow

It appears that this issue arose when the authors of the assignR package altered assignR::calRaster -- some time between v2.1.1 and 1.2.1 (we developed this software under the latter release). One can check the assignR version using sessionInfo(). Running the following code appears to fix the error:

devtools::install_version("assignR", version = "1.2.1", repos = "http://cran.us.r-project.org")
library(assignR) 
sessionInfo() # confirm assignR_1.2.1
data(d18o_world)
