• updated test standards after changes to koRpus' internal calculations of numer of lines in texts imported from TIF data frames

changed

• kRp.corpus: replaced prototype() in class definition with initialize method

• docTermMatrix() : results were wrong because numbers were assigned to wrong columns; now fixed in koRpus

• unit tests failed on windows due to an UTF-8 issue

changed

• the nested object class kRp.hierarchy was replaced by kRp.corpus; instead of reproducing the file hierarchy in the object structure, kRp.corpus has a flat structure with all texts in one single data frame; this data frame was also renamed from "TT.res" into "tokens" the class name kRp.corpus was used in tm.plugin.koRpus before and is just being recycled ;) kRp.corpus inherits from class kRp.text as defined in the koRpus package

• status messages are currently only shown when only one CPU is used

• corpusTagged() : now called taggedText() as in koRpus

• corpusDesc() : now called describe() as in koRpus

• [, [<-, [[ and [[<- methods no longer apply to the summary data frame but tokens slot as in koRpus (where it applies to the TT.res slot)

• show() : kRp.corpus objects now list all available features

• read.corp.custom() : removed unused mc.cores argument

• docTermMatrix() : by default behaves like most other methods and adds its result to the input object rather than returning just the matrix; also, the generic is now defined by the koRpus package and was removed, including all of the actual function code

• adjusted unit tests and vignette

• updated all examples to use a new sample corpus (see added), to the benefit that many "\dontrun{}" cases could be removed

added

• readCorpus() : the hierarchy levels of a text corpus can now be assumed directly from the directory structure by setting "hierarchy=TRUE"

• corpusHasFeatures() , corpusHasFeatures() <-, corpusFeatures() , corpusFeatures() <-, corpusHierarchy() , corpusHierarchy() <-, corpusCorpFreq() , corpusCorpFreq() <-, diffText() , diffText() <-, originalText() : new getter/setter methods for kRp.corpus objects

• split_by_doc_id() : new method transforms a kRp.corpus object into a list of kRp.text objects

• corpusDocTermMatrix() : new method to get/set the sparse document term matrix in kRp.corpus objects

• [[/[[<-: gained new argument "doc_id" to limit the scope to particular documents

• describe() /describe()<-: now support filtering by doc_id

• new sample corpus for use in examples

removed

• removed all classes and methods dealing with kRp.hierarchy

• removed deprecated methods of the pre-kRp.hierarchy era

• removed generic of tif_as_tokens_df() as it was moved to the koRpus package

• readCorpus() : solved a cryptic warning when more than one text was tokenized

added

• docTermMatrix() : new method to generate document-term matrices, either with absolute frequencies or tf-idf values

• query() : new method, extending the generic of koRpus >= 0.12-1

• filterByClass() : new method, extending the generic of koRpus >= 0.12-1

• jumbleWords() : new method, extending the generic of koRpus >= 0.12-1

• clozeDelete() : new method, extending the generic of koRpus >= 0.12-1

• cTest() : new method, extending the generic of koRpus >= 0.12-1

• textTransform() : new method, extending the generic of koRpus >= 0.12-1

• show() : new method for objects of class kRp.hierarchy

changed

• depends on koRpus >= 0.12-1 now

• depends on the Matrix package now (for docTermMatrix() )

• adjusted test standards to include the additional POS tags from koRpus >= 0.12-1

• readCorpus() , kRpSource() : added missing imports from packages tm, NLP and parallel

• readCorpus() : fixed status message formatting

• corpusTm() : removed useless "level" argument and corrected the output

• readCorpus() : removed unused "level" argument

• corpusFiles() : now also works with flat hierarchy objects

added

• readCorpus() : can now also import data frames in TIF format, including support for hierarchal categories

• tif_as_corpus_df() : new S4 method to transform a kRp.hierarchy object into a TIF compliant data frame

changed

• readCorpus() : the tm corpora now include full hierarchy metadata

• removed pre-hierarchy portions from internal function whatIsAvailable()

• vignette: also includes info on readCorpus()

• tests: adjusted test standards to new object class

added

• kRp.hierarchy: new S4 class to replace kRp.sourcesCorpus and kRp.topicCorpus to allow more generic nesting of hierarchical levels

• readCorpus() : new function to generate kRp.hierarchy objects recursively

• many corpus*() getter functions can now filter by hierarchy level or category ID

• removed all code regarding simpleCorpus() , sourcesCorpus() and topicCorpus() , their object classes and methods; this is all handled much more flexible by kRp.hierarchy and readCorpus() now

• sourcesCorpus() : speak of "text" instead of "texts" if it's only one

changed

• adjusted package to support koRpus >= 0.11 and sylly, especially with regards to summary() , hyphen() , and new class contructors

• summary() : for more coherence with the koRpus package the "text" column in the summary slot was renamed into "doc_id"

• reaktanz.de supports HTTPS now, updated references

• vignette is now in RMarkdown/HTML format; the SWeave/PDF version was dropped

• hyphen() /lex. div() /readability(): 'quiet' is now TRUE by default

• lex.div() : 'char' is now an emtpy string by default; computing all characteristics was not a useful default for large text corpora

added

• README.md

• new [, [<-, [[ and [[<- methods added for corpus object classes

• new methods tif_as_tokens_df() to export corpus objects as a single data.frame in fully TIF compliant format

• summary() : now also includes the total number of stopwords (if available)

• new class object contructors kRp_corpus() , kRp_sourcesCorpus() , and kRp_topicCorpus() can be used instead of new( "kRp.corpus" , ...) etc.

• the arguments that simpleCorpus() was supposed to pipe to DirSource() weren't used

changed

• the "paths" argument of topicCorpus() now expects a list, not a vector

• using the parallel package to be able to use more CPU cores

added

• new argument "format" for simpleCorpus() , sourceCorpus() , and topicCorpus() , to be able to work with text objects directly, instead of files

• using the S4 methods of koRpus 0.06-1 now, therefore renamed all methods removing the *.corpus suffix (e.g., lex.div.corpus() is now lex.div() )

• renamed classes into kRp.corpus, kRp.sourcesCorpus and kRp.topicCorpus, and their generator functions accordingly

added

• new methods read.corp.custom() , freq.analysis() and summary()

• new getter/setter methods: corpusSources() , corpusTopics() , corpusFreq() , corpusSummary()

• first basic unit tests, using the testthat package

• new option "summary" for lex.div() and readability() , to automatically update the summary data.frames

• first notes in a vignette

• initial release
