Function to generate a PDF with four panels per page, showing some basic item characteristics.
itemInspection(dat, items,
docTitle = "Scale inspection", docAuthor = "Author",
pdfLaTexPath, rnwPath, filename="itemInspection",
convertFactors = TRUE, digits=4)Dataframe containing the items of the relevant scale
Either a character vector with the itemnames, or, if the items are organised in scales, a list of character vectors with the items in each scale.
Title to use when generating the PDF.
Author(s) to include when generating the PDF.
The path to PdfLaTex. This file is part of a LaTeX installation that creates a pdf out of a .tex file.
In Windows, you can download (portable) MikTex from http://miktex.org/portable. You then decide yourself where to install MikTex; pdflatex will end up in a subfolder 'miktex\bin', so if you installed MikTex in, for example, 'C:\Program Files\MikTex', the total path becomes 'C:\Program Files\MikTex\miktex\bin'. Note that R uses slashes instead of backslashes to separate folders, so in this example, pdfLaTexPath should be 'C:/Program Files/MikTex/miktex/bin'
In MacOS, you can install MacTex from http://tug.org/mactex/ By default, pdflatex ends up in folder '/user/texbin', which is what pdfLaTexPath should be in that default case.
In Ubuntu, you can install TexLive base by using your package manager to install texlive-latex-base, or using the terminal: 'sudo apt-get install texlive-latex-base' In ubuntu, by default pdflatex ends un in folder '/usr/bin', which is what pdfLaTexPath should be in that default case.
The path where the temporary files and the resulting PDF should be stored.
The filename to use to save the pdf.
Whether to convert factors to numeric vectors for the analysis.
The number of digits to use in the tables.
This function returns nothing; it just generates a PDF.
