getCqItanal function

getCqItanal

helper function to return list of lists, each list relates to one generalised item from an ACER ConQuest itanal output. Each list contains: (1) item-total and item-rest correlations ....

getCqItanal(sysFile, matrixPrefix = NULL, isDebug = FALSE)

Arguments

• sysFile: An ACER ConQuest system file.

• matrixPrefix: The name of the itanal analysis defined in ACER ConQuest. For example, in ACER ConQuest syntax itanal ! matrixout = itan, ... ;

  the value of matrixPrefix is "itan". Note, this is required as an ACER ConQuest system file can contain outputs from several calls to itanal. A common use, for example, is to call itanal

  for an overall analysis, and a second call to itanal for group-level analysis.

• isDebug: A boolean to toggle on or off debug output

Returns

A list.

Examples

myItanal <- getCqItanal()
print(myItanal[[1]])
