oneRow {heuristica}

Convenience function to get one row from a matrix or data frame.

Description

This simply calls matrix_or_data_frame[row_index,,drop=FALSE] for you but is shorter and helps you avoid forgetting drop=FALSE. The need for drop=FALSE when selecting just one row is explained here: http://www.hep.by/gnu/r-patched/r-faq/R-FAQ_56.html
