mirtCAT_preamble
(Package: mirtCAT) :
Preamble function called by mirtCAT
This is largely an internal function called by mirtCAT, however it is made public for better use with external web-hosting interfaces (like http://www.shinyapps.io/). For more information see http://shiny.rstudio.com/articles/persistent-data-storage.html for further information about saving output remotely when using shiny.

generate.mirt_object
(Package: mirtCAT) :
Generate a mirt object from population parameters
This function generate a mirt object from known population parameters, which is then passed to mirtCAT function for running CAT applications.

createShinyGUI
(Package: mirtCAT) :
Function returning an object used by shiny
This function returns the GUI setup results by calling shinyApp. Primarily, this is only useful when hosting the application publicly, such as through http://www.shinyapps.io/. The function mirtCAT_preamble must be run before this function is called. The object is executed by calling runApp.

A function that returns the next item in the computerized adaptive test. This should be used in conjunction with the updateDesign function. The raw input forms can be used when a customNextItem function has been defined in mirtCAT.

getPerson
(Package: mirtCAT) :
Retrieve person object after running createShinyGUI
This function returns a suitable person object identical to the result returned by mirtCAT, and is only required when the GUI is launched by the createShinyGUI method.

mirtCAT
(Package: mirtCAT) :
Generate an adaptive or non-adaptive test HTML interface
Provides tools to generate an HTML interface for creating adaptive and non-adaptive educational and psychological tests using the shiny package. Suitable for applying unidimensional and multidimensional computerized adaptive tests using item response theory methodology. Test scoring is performed using the mirt package. However, if no scoring is required (i.e., a standard survey) then defining a mirt object may be omitted.

Generate a CAT pattern given various inputs. Returns a character vector or numeric matrix (depending on whether a df input was supplied) with columns equal to the test size and rows equal to the number of rows in Theta. For simulation studies, supplying a Theta input with more than 1 row will generate a matrix of responses for running independent CAT session when passed to mirtCAT(..., local_pattern).
