Error in if (prop == 0) { : missing value where TRUE/FALSE needed if NAs not removed

[TheTams]

I have created an object 'Rob_extr' using the extraction function.
It has columns of ind_id, tax (genera), sub (genus-species), lat, lan, cells, the 19 bioclim colnames.
As generated, it runs as below:

Rob_mcr <- MCR(Rob_extr, method = 'unweight', plot = FALSE)
Error in if (prop == 0) { : missing value where TRUE/FALSE needed

If I run, the below, it appears to work.

Rob_extr_rmna <- na.omit(Rob_extr)
Rob_mcr <- MCR(Rob_extr_rmna, method = 'unweight', plot = FALSE)

The NAs in this case are in the climate variable columns. I think they are likely generated by coastal or island observations that are classified as non-land in the worldclim 10m data. There are no Nas in 'tax'.

Should na.omit be run over the extraction file 'in code'?
A note to users to do so be added to the documentation?

I think an na.omit() in the extraction function is sensible. That's fixed in the latest commit: 54d2d78
