scaleDiagnosisToPDF: scaleDiagnosisToPDF

Description

scaleDiagnosis provides a number of diagnostics for a scale (an aggregative measure consisting of several items), and scaleDiagnosisToPDF takes the resulting object and generates a PDF file, which is then saved to disk.

Usage

scaleDiagnosisToPDF(scaleDiagnosisObject,
                    docTitle = "Scale diagnosis", docAuthor = "Author",
                    pdfLatexPath, rnwPath=getwd(),
                    filename = "scaleDiagnosis",
                    digits=2,
                    rMatrixColsLandscape = 6,
                    pboxWidthMultiplier = 1,
                    scatterPlotBaseSize = 4,
                    maxScatterPlotSize = NULL,
                    pageMargins=15,
                    pval=TRUE)

Arguments

scaleDiagnosisObject

An object generated by scaleDiagnosis.

docTitle

The title of the PDF file (printed on the first page).

docAuthor

The author to show in the PDF file (printed on the first page).

pdfLatexPath

The path to PdfLaTex. This file is part of a LaTeX installation that creates a pdf out of a .tex file. See rnwString for more information.

rnwPath

The path where the temporary files will be stored.

filename

Filename of the PDF (".pdf" is appended).

digits

Number of digits to show.

rMatrixColsLandscape

This number determines when the page(s) in the PDF is/are rotated; pages with matrices that have this number of columns or more are rotated.

pboxWidthMultiplier

Passed on to (unexported method) print.rMatrix.

scatterPlotBaseSize

Basic size of scatterplots in centimeters. If this number, multiplied by the number of items (i.e. columns/rows in scattermatrix) is larger than maxScatterPlotSize, it is ignored.

maxScatterPlotSize

Maximum size of scatterplots; automatically calculated if NULL.

pageMargins

Margins of landscape pages in millimeters.

pval

Whether to print p-values using the p-value formatting. Passed on to (unexported method) print.rMatrix.

Value

Nothing is returned; the file is printed to disk.

Details

This functon generates a PDF file from a scaleDiagnosis object. scaleDiagnosis generates an object with several useful statistics and a plot to assess how the elements (usually items) in a scale relate to each other, such as Cronbach's Alpha, omega, the Greatest Lower Bound, a factor analysis, and a correlation matrix.

Examples

Run this code

# NOT RUN {
# }
# NOT RUN {
### Generate a datafile to use
exampleData <- data.frame(item1=rnorm(100));
exampleData$item2 <- exampleData$item1+rnorm(100);
exampleData$item3 <- exampleData$item1+rnorm(100);
exampleData$item4 <- exampleData$item2+rnorm(100);
exampleData$item5 <- exampleData$item2+rnorm(100);

### Use all items and create object
scaleDiagnosisObject <- scaleDiagnosis(dat=exampleData);

### Generate a PDF
scaleDiagnosisToPDF(scaleDiagnosisObject);
