The jmvReadWrite package provides two functions: jmvRead and jmvWrite.
The free and open a statistical spreadsheet 'jamovi' (www.jamovi.org) aims to makes statistical analyses easy and intuitive. 'jamovi' produces syntax that can directly be used in R (in connection with the R-package 'jmv'). Having import / export routines for the data files generated by 'jamovi' ('.omv') permits an easy transfer of analyses between 'jamovi' and R.
