Validate a hipercow_resources list for a driver.
Source: R/resource.R
hipercow_resources_validate.RdQuery a driver to find information about the cluster, and then validate a hipercow_resources list against that driver to see if the resources requested could be satisfied.
Arguments
- resources
A hipercow_resources list returned by hipercow_resources, or
NULL- driver
The name of the driver to use, or you can leave blank if only one is configured (this will be typical).
- root
The hipercow root
