readbulk is an R package that facilitates loading multiple data files with a similar structure and combining them into a single data.frame, using the read_bulk function. It wraps most common R functions for reading data, retaining the flexiblity of the available tools.

For (experimental) psychologists, the package provides the read_opensesame function which wraps the above, providing the appropriate defaults for loading the many files created by OpenSesame.
