Research direction
No files or tests are named. Start by locating how colClasses and type promotion are handled in the data.table codebase, then trace the import path for inconsistent column values. Done means an option preserves the requested data types, coerces inconsistent values to NA, and reports the affected columns.
Written by the indexing model from the issue text.
Description
Option to respect colClasses data type specification i.e. no bumping. Any inconsistencies could be forced to NA and these problematic columns would be reported.
Often I get artefacts in second hand data which force a numeric to character bump which is not desired.
