`join-datagen.R` expects 4 arguments but only 3 are provided in `format_and_mount` script

[andygrove]

Here is a part of format_and_mount.sh:

echo "Creating 500mb join datasets"
Rscript ../_data/join-datagen.R 1e7 0 0
Rscript ../_data/join-datagen.R 1e7 5 0
Rscript ../_data/join-datagen.R 1e7 0 1

This fails:

Creating 500mb join datasets
Error: sort %in% c(0L, 1L) is not TRUE
Execution halted

join-datagen.R expects 4 arguments but only 3 are provided.
