fixed

• properly adjusted imports of functions/methods from other packages

changed

• dropped dependencies on polycor and psychometric, item analysis is now bone using psych::alpha()

• removed outdated internal klausuR-internal.roxy.all.R file

Changes in klausuR version 0.12-12 (2018-07-29)

fixed

• the option 'keep.cases' in klausur.data() was broken

• klausur.report(): fixed LaTeX issue if percent sign was used in psedonyms

changed

• klausur.report(): global reports are now printed in landscape mode

• reaktanz.de supports HTTPS now, updated references

• the source code has moved from R-forge to https://github.com/unDocUMeantIt/klausuR

Changes in klausuR version 0.12-11 (2016-06-29)

added

• new argument "fancyhdr" in klausur.report() to add information to headers and footers of generated reports

changed

• cleaned up klausur.report(): moved internal functions to separate file

• adjusted the auto table sizes in klausur.report() a bit

• rephrased the description to comply with CRAN terms

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 from sort() 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

• polycor was added as a dependency (needed for distractor analysis)

• 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

• pdfLaTeX became picky and didn't work with the table of marks any more. set print.xtable() to use floating=FALSE to fix this.

• 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)

changed

• no real new features, restructured the source code layout, as roxygen2 doesn't seem to get collate info easy with R 3.0.0 ...

Changes in klausuR version 0.12-7 (2013-01-25)

fixed

• 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

Changes in klausuR version 0.12-4 (2012-02-09)

• 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

Changes in klausuR version 0.12-3 (2011-10-04)

• 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

Changes in klausuR version 0.12-2 (2011-09-11)

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 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)

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()

• fixed annoying "show" warning

Changes in klausuR version 0.10-1 (2011-02-14)

• 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

Changes in klausuR version 0.10-0 (2010-11-03)

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