replaced custom function to clean up LaTeX code with encoded_text_to_latex() from tools package in klausur.report()

replaced UTF-8 characters with \uxxxx escapes in klausur.report()

set some internal variables NULL in compare() , grand.table() , klausur.gen() , klausur.mufo() , klausur.report() and the internal function klausur.reorderItems() , to avoid needless NOTEs from "R CMD check"

re-formatted the ChangeLog to have the roxyPackage translate it into a NEWS.Rd file

fixed bug in compare() : "new.set" didn't work if exactly one or none differences were found

added 'maxp' option to klausur.answ-class and klausur.date() , to be able to compensate for really buggy tests...

adjusted klausur() to check for maxp

added option "merge" to klausur.report() , to merge all individual reports into one file

added status feedback to klausur.report() , can be turned of with new option "quiet=TRUE"

updated the RKWard GUI to the new options

fixed bug in nret.rescale() regarding NR data

fixed author definition for R 2.14

cleaned the docs so package check runs fine

fixed typo in klausur.report()

0.12 is not fully downward compatible with earlier versions of the klausuR package!

drastic changes: klausur() and klausur.mufo() from now on only take objects of the new class klausur.answ, which replaces the 'answ' and 'corr' arguments completely. Most of the time it took to evaluate tests was squeezing data with exotic variable names and loads of surprises into a valid data.frame. Those days should finally be numbered now...

added function klausur.data() to do the squeezing into klausur.answ class objects (s.o.)

added scoring function NRET+, which is more conservative than NRET when it comes to errors

added function nret.rescale() to change scaling of points in result objects (NR/ET/NRET/NRET+)

added function grand.table() to export all results back to CSV format

the class klausuR gained a new slot 'misc' to preserve whatever unused variables are left over from the squeezing process.

introduced class klausuR.test, now as a placeholder for future releases, and added slots to classes klausuR and klausuR.answ

added function nret.translator() to convert NRET/ET data from/to SPSS

added options 'table.size' and 'NRET.legend' to klausur.report()

smarter handling of histograms and marks info in klausur.report()

klausur.report() can now also create histograms with data from several klausuR objects

klausur.report() can now produce reports from more than one object, if you give them in a list

klausur.compare() was renamed to compare() and can now cope with NAs, unequal cases and unequal variables (will cause verbose warnings), and rename input variables, if necessary. it is also no longer limited to compare klausuR data, hence the renaming.

fixed some NRET/ET related bugs in the plot method and klausur.gen.marks()

fixed 'if' statement error in show method for klausuR-class objects

added support for item analysis on ET/NRET data

added NRET sample data "spss.data"

added SD values to item analysis (show method)

added 'sort.by' option to klausur.data() , and klausur()

added sort method for objects of class klausuR

added the full RKWard plugin as inst/rkward, so both get updated simultanously

adapted rkwardtests to current behaviour of klausuR

sources can now be roxygenized by roxygen2 (classes docs are static until '@slot' is supported again)

aligned penalty for false negatives to number of correct alternatives in NRET/ET scoring

for NRET/ET, moved determination of max. points etc. to new internal function nret.minmax()

added internal function roxy.package() to ease development

added initial support for elimination testing (ET) and number right elimination testing (NRET)

fixed "Form" addition in klausur.gen()

fixed bug in points (were logical instead of numeric, which caused trouble for PDF generation)

fixed annoying "show" warning

complete rewrite of klausur.compare() : less and more efficient code

replaced "na.replace" option with a plain "na.rm" , i.e., NA cases are dropped completely by default

added new "na.rm" option to plot method, TRUE by default

added variable "Form" to klausur.gen()

replaced several "if(a == b)" constructs with "identical(a, b)" or "isTRUE(...)"

fixed: klausur.report() accidently created PDFs in a loop over and over again

fixed: klausur.report() failed if "#" appeared in names

fixed: klausur.report() didn't show partial results correctly, added check for needed digits

added slots "wght" and "points" to class klausuR

added klausur.mufo() and new S4 class klausuR.mult: initial support for parallel test forms

added show() and plot() methods for objects of class klausuR.mult

added support for objects of class klausuR.mult in klausur.report()

fixed missing import of tools package

dropped roxygen dependency (still using roxygen, though)

some code cleanup for better readability

added direct PDF creation to klausur.report() , using texi2dvi() from package tools

consequently added the tools package as a dependency

added schemes "DIHK" , "USA" and "UK" to klausuR.gen.marks()

added informative slot "marks.sum" to objects of class klausuR

updated the show method for klausuR objects accordingly

added "marks.info" option to klausur.report() , to include all or parts of "marks.sum" if wanted

fixed another bug in klausur.compare() : objects with NAs meant trouble.

added "select" option to klausur.compare() to be able to focus on certain variables

added support for different file name scheme to klausur.report() (matr. no. or name_firstname)

added "alt.comma" parameter to klausur.report()

minor corrections in the documentation (some missing params in usage)

restructured the LaTeX output

fixed some bugs in klausur.compare()

added parameters to skip cronbach's alpha and item analysis in klausur()

cronbach's alpha and item analysis now run in a safe tryCatch() environment

modified the show() method accordingly

added "alpha if removed" calculation for each item

added longtable support for klausur.report()

fixed some bugs in klausur() , klausur.report() and plot() regarding character vectors

added support for partially correct answers (if multiple correct answers possible) via the new "score" parameter

more cleaning up: moved some subroutines to internal functions

added marks A to F as an option in klausur.gen.marks()

adjusted the plot method to treat marks as characters

beautyfied the output of individual results in klausur()

cleaned up a bit (removed unused relicts from klausur.R)

translated hopefully all comments in the code into english

added feature to suggest marks by normal distribution

initial public release (via reaktanz.de)
