setImageDefs(def, verbose = TRUE)There are two main components to specifying output formats: style definitions and style assignments. The definition has the specific components (such as a table cell) and their format values (e.g. boxed with solid black lines). The function getStyleDefs can fetch the pre-existing styles in the package. These can be modified and new definitions can be added. The function setStyledefs ``registers'' the style changes with the package. When odfWeave is called, these definitions are written to the style sections of the XML files. See the example below.
There is a second mechanism to assign styles to specific output elements. The functions getStyles and setStyles can be used to tell odfWeave which style definition to use for a particular output.
For example, the input and output elements control how R code and command--line output look. To change either of these, an existing definition can be assigned to these entries and reset using setStyles(currentStyles). Unlike the style definitions, the style assignments can be modified throughout the R code.
For graphics, getImageDefs and setImageDefs can be used to
specifiy the type of plot device and it's arguments. getImageDefs
will return a list with elements
capabilities is used to make that determination by
defaultplotHeightdispHeightSince these functions can be called from within code chunks, graphical parameters can be changes during the Sweave process.
currentStyleDefs <- getStyleDefs()
currentStyleDefs$ArialNormal$fontSize <- "10pt"
