Changes in klausuR version 0.12-10 (2015-02-07)
added
- support for pick-n scoring was added to - klausur()
- new slot - "distractor.analysis"in objects of class klausuR, listing the selected answer alternatives for each individual item and some statistics like correlation with the overall results and mean results of subjects chosing an alternative
- new element - "wrong"in slot- "corr"of klausur.answ class items for pick-n scoring
- new argument - "wrong"in- klausur.data()for the same reason
-  klausur.report()gained options fromsort()for"anon"and"glob"results
- new elements - "keep.cases"and- "recode.na"in- klausur.data(), to keep cases with missing data, even if "na.rm=TRUE"
fixed
- stripping trailing whitespace from answer data if it is in factor of character format. this happens easily if data was imported from SPSS and can cause nasty problems, because the whitespace characters are interpreted by - klausur()as a valid but wrong answer
- removed typos in - klausur.repost()code (- "appen"instead of- "append")
- anonymous feedback output is now sorted by points as a default. the previous default took the order as is, which usually sorted it by family names of participants, which limits anonymity to a certain degree 
- the character "'" is now also filtered out of file names 
- breaks for axis labels in histograms are now calculated by internal function - axis.breaks(), which fixes a problem with non-integer points
-  klausur.report()does now also check for digits to display in global and anonymous feedback PDF
-  klausur.report()now shows empty answers ("") as empty, not as a question mark
- LaTeX replacements of characters has been corrected to also match first character 
- manual setting of - "table.size"was buggy in- klausur.report(), adding just the word of the chosen size to the table
-  klausur.mufo()was using outdated object classes
changed

- some code cleaning in - klausur()for better readability
- added a proper GPL notice at the beginning of each R file 
- replaced all tabs in the source code by two space characters 
- moved the internal helper function - find.partial()out of the function body of- partial()for cleaner code
- show method for klausuR results now also reports distractor analysis, if found 
- partial points are no longer rounded before end results are calculated 
Changes in klausuR version 0.12-9 (2013-08-05)
fixed

- added some more character filtering on generated filenames which could cause LaTeX to fail with an error 
Changes in klausuR version 0.12-8 (2013-05-08)

Changes in klausuR version 0.12-0 (2011-08-30)
- 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 tocompare()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) 
Changes in klausuR version 0.11-3 (2011-06-19)
- 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 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
