Hi guys, I was thinking that at some stage we could switch from using read.csv in the move function to the fread function. The ctmm package also provides wrappers for reading gz using fread. It would speed up the import of large files considerably. I also talked to Chris Fleming and he said we could take their code and replicate (citing their programmer in the code). It would not break anyone's code, I think and be nice to have that speeds up the imports.
