OpenRepGrid: internal functions overview for developers. This page is a help for developers: these functions are usually not needed by the casual user. The internal functions have a twofold goal 1) to provide means for advanced numerical grid analysis and 2) to facilitate function development. The function for these purposes are internal, i.e. they are not visible in the package documentation. Nonetheless they do have a documentation that can be accesses in the same way as for other functions. More in the details section.
Functions for advanced grid analysis
The package provides functions to facilitate numerical research for grids.
These comprise the generation of random data, permutation of grids etc.
to facilitate Monte Carlo simulations, batch analysis of grids and other methods.
With R as an underlying framework, the results of grid analysis easily lend
themselves to further statistical processing and analysis within R.
This is one of the central advantages for researchers compared to other
standard grid software. The following table lists several functions for these purposes.

Modules for function development
Beside the advanced analysis feature the developer's functions comprise
low-level modules to create new functions for grid analysis.
Though the internal structure of a repgrid object in R is simple
(type e.g. str(bell2010, 2)
to get an impression), it is convenient
to not have to deal with access on this level. Several function like e.g.
getElementNames
are convenient wrappers that perform standard tasks
needed when implementing new functions. The following table lists several
functions for these purposes.

getNoOfConstructs | |

Currently the OpenRepGrid development team is Mark Heckmann. Everyone who is interested in developing the package is invited to join.
The OpenRepGrid package is developed at R-Forge (http://openrepgrid.r-forge.r-project.org). The R-Forge site provides information and mailing lists for help queries and bug reports. Bug reports can also be emailed to the package maintainer or issued under http://www.openrepgrid.org. The maintainer at R-Forge is Mark Heckmann <heckmann(at)uni-bremen.de>.
