Extracts statistical references from a directory with HTML and PDF files. The "pdftotext" program is used to convert PDF files to plain text files. This must be installed and PATH variables must be properly set so that this program can be used from command line.

See statcheck
for more details. This function is a wrapper around both checkPDFdir
for PDF files and checkHTMLdir
for HTML files.
Depending on the PDF file the comparison operators can sometimes not be converted correctly, causing these to not be reported in the output. Using html versions of articles is reccomended for more stable results.
Note that the conversion to plain text and extraction of statistics can result in errors. Some statistical values can be missed, especially if the notation is unconvetional. It is recommended to manually check some of the results.

Source |
Name of the file of which the statistic is extracted |
Statistic |

df1 |
First degree of freedom |
df2 |

Value |

Reported.Comparison |

Reported.P.Value |
The reported p-value, or NA if the reported value was NS |
Computed |
The recomputed p-value |
Raw |

InExactError |
