The hdfqlr package for R provides an API for HDF file access using HDFql. In order to use this package, you will need to download HDFql for your system. See the Quick Start vignette to get started.

NOTE 7/10/2019: The HDFql 2.1.0 release contains a minor but necessary change in the R wrapper, specifically in the .Call() specifications for accessing C functions in the HDFql library. hdfqlr will not correctly load prior versions of HDFql.
