Text: Fixed error that caused R to crash during garbage collection.
        This may have been due to a mysterious interactions between
        Rcpp and gc, but I am not sure what it was. Changing the type
        of returned object from Rcpp::List to SEXP fixed it.

Version: 0.1.1

Category: Implementer: Antti Arppe <antti.arppe@iki.fi
Text: General: general modifications and fixes to several functions to
        check the integrity of input (mainly argument 'cuesOutcomes'),
        and otherwise with deal with diverse input formats with less
        hickups; new function 'predict.ndlClassify'; user-specifiable
        scalability for dealing with really large input files when
        using the C code method for the calculation of Cue-Cue and
        Cue-Outcome co-occurrences; maintainer e-mail address modified
        to a generic one.

Text: acts2probs.R (acts2probs): code modified internally so that a
        minimum activation value of 'acts.minimum.correction=1e-10' is
        used instead when any activation value is exactly equal to 0 in
        input 'acts' (due to lack of any previously observed cues in
        input to e.g. 'estimateActivations').

Text: coocMatrices.c (cooc): C code fixed so that it will work with
        space characters ' ' in Cues and Outcomes (as input
        'cuesOutcomes' to 'estimateWeights', 'cooccurrencesCues' and/or
        'cooccurrencesCuesOutcomes') - due to this fix the 'Outcomes',
        'Cues' and 'Frequency' columns are now separated by single
        tabulator characters '\t' (instead of spaces ' ') in the
        temporary text file: 'ndl_410025912.txt' through which data is
        passed to the C code from the 'estimateWeights',
        'cooccurrencesCues' and 'cooccurencesCuesOutcomes' functions ;
        C code modified so that the sizes of Cues and Outcomes (and
        their combinations) can be specified flexibly by the user in
        'estimateWeights', 'cooccurrencesCues' and/or
        'cooccurrencesCuesOutcomes' beyond the default values
        (max.cues=20000, max.characters=20000, max.lines=500000;
        communicated via the temporary parameter file:
        'ndl_par_410025912.txt'), which will allow the use of the C
        code alternative (with 'method="C"') via greater memory
        allocation for very large data sets on servers with
        (sufficient) greater capacity; C code modified so that upon
        encountering errors (not finding the parameter or data text
        files, or the data file exceeding 'max.lines'), which normally
        will all be detected by the calling R functions but can occur
        if the C code is called directly, an appropriate error message
        will be output to: 'ndl_err_410025912.txt' and the execution
        will end gracefully with 'return' (instead of 'exit').

        'cuesOutcomes'can be specified by the user beyond the default

Text: estimateActivations.R (estimateActivations): code and output
        values changed so that previously unseen Cues and Outcomes in
        input 'cuesOutcomes' are included in the output values, in
        addition to 'activationMatrix', as 'newCues' and 'newOutcomes',
        instead of these being printed to standard output; in the case
        of such unseen Cues or Outcomes a warning message is now
        output; code modified so that a warning message is output if
        potential accidental 'NA' strings (resulting from
        'as.character(NA)') are detected among the input Cues and
        Outcomes in 'cuesOutcomes'; code will stop with an error
        message if any actual NA's are encountered among Cues and
        Outcomes in 'cuesOutcomes'.

        communicated via the temporary parameter file:

        message if accidental empty cues (string-initial or
        string-final, or multiple string-medial underscores '_'), or
        NA's are detected in Cues or Outcomes in 'cuesOutcomes'; a
        warning message is output if potential accidental 'NA' strings
        (resulting from 'as.character(NA)') are detected among the
        input Cues and Outcomes in 'cuesOutcomes'; code modified
        internally so that Cues and Outcomes in 'cuesOutcomes' are
        coerced to character strings, in case they might be input as
        factors (which may happen by default when reading data with
        'read.table' or 'read.csv' into R from an external plain text
        or CSV file as a data frame); global option
        "ndl.estimateWeights" specified as TRUE so that the auxiliary
        functions 'cooccurrenceCues' and 'cooccurrenceCuesOutcomes'
        will not rewrite the input text file: 'ndl_410025912.txt';
        after successful execution, "ndl.estimateWeights" again
        specified as NULL.
