Basic package handling

Loading the package
To make the functions of the OpenRepGrid package available in R it has to be loaded (for previous installation see ...). This step has to be done each time you start R.

library(OpenRepGrid)

Accessing the documentation
Now you can use all the functions contained in the package. To gain an overview over all the functions available a documentation is included in the package. The package's documentation files can be accessed via one of the following commands. ?OpenRepGrid		# or help("OpenRepGrid")

This will open the package's documentation.

If you click on "index" you will see a list of all functions.

The package documentation contains information on all user-accessible functions and data sets that are contained in the package and can be used to analyze repertory grids. To directly open a function's or data set's documentation one of the two following commands can be used.

?name_of_function_or_dataset		# or help(name_of_function_or_dataset)

E.g. to open the help file for the function constructCor click the corresponding entry in the function list or type ?constructCor  #or help(constructCor)

The figure shows the help file for the function. All documentation files have the same structure:
 * Description: Some backgroud information about the function and a description of what it does.
 * Usage: How to write the function call into the console and the order of the possible argumnets that can be specified.
 * Arguments: An explanation of what arguments can be modified and what they mean.
 * Value: What kind of object is returned by the function
 * Examples: Some code you can type directly into the console. Usually this is the best way to star and to see what a function does.
