HTMLplot: Insert a graphic into an HTML output

In R2HTML: HTML exportation for R objects

Description

Exports the active graphic to a JPEG or GIF file and add it to a target HTML output, by writing the <IMG> tag.

Usage

HTMLplot(Caption = "", file = get(".HTML.file"), append = TRUE,
  GraphDirectory = ".", GraphFileName = "", GraphSaveAs = "png",
  GraphBorder = 1,  Align = "center", Width = 500, Height = 500,
  WidthHTML = NULL, HeightHTML = NULL, GraphPointSize = 12,
  GraphBackGround = "white", GraphRes = 72, plotFunction = NULL, ...)

Arguments

Caption	text to be placed below the graphic, as a caption
file	the target HTML file
append	logical. If 'TRUE' output will be appended to 'file'; otherwise, it will overwrite the contents of 'file'
GraphDirectory	path where file should be stored
GraphFileName	name of the file to produce (could be missing)
GraphSaveAs	an existing exportation device, such as jpg or gif
GraphBorder	HTML border option for the <IMG> tag
Align	HTML align option for the <IMG> tag
Width	width of the image to create (passed to the driver)
Height	height of the image to create (passed to the driver) (NULL: not specified)
WidthHTML	Width of the image in HTML
HeightHTML	Height of the image in HTML (NULL for not specified)
GraphPointSize	To be passed to the device creator function
GraphBackGround	To be passed to the device creator function
GraphRes	To be passed to the device creator function
plotFunction	Function to be evaluated for the on-the-fly creation of the graph to be exported
...	...

Details

Note that this function is coded to work automatically when using automatic exportation with HTMLStart. When using manualy, user should pay attention to the GraphDirectory option, so that graph files are in the same directory as HTML output files. When using to write reports in a non interactive way, first generate the graphic using a device and then use HTMLInsertGraph.

Value

no value returned.

Note
