devSVGTips {RSVGTipsDevice} | R Documentation |
This function starts up an SVG graphics device that will write to a file. The SVG shapes have optional tooltips and/or hyperlinks.
devSVGTips(file = "Rplots.svg", width = 10, height = 8, bg = "white", fg = "black", onefile=TRUE, xmlHeader=FALSE, useStyleAttributes=FALSE, toolTipMode = 1, toolTipFontSize = 10, toolTipOpacity = 1.0, title = "R SVG Plot", sub.special=TRUE)
file |
the file where output will appear |
width |
The width of the plot in inches |
height |
the height of the plot in inches |
bg |
the background color for the plot |
fg |
the foreground color for the plot |
onefile |
merge plot calls into onefile or separate them to separate pages |
xmlHeader |
Print XML header or not (it is recommended to not print a header) |
useStyleAttributes |
Specify shape attributes in a
style attribute or as plain attributes (plain attributes is recommended) |
toolTipMode |
Mode of toop tips: 0 (no tool tips), 1, or 2 (number of lines of tool tip) |
toolTipFontSize |
Size of font in tool tips (in points/pixels) |
toolTipOpacity |
Opacity of toop tips: between 0 and 1. A value of 0.9 allows the image behind the tooltip to be seen, but can render slowly on some viewers |
title |
Title of plot |
sub.special |
Unless sub.special=FALSE , special SVG
characters (ampersand, less-than, etc.) in title will be substituted by the
appropriate XML encoding (if these substitutions are not made, it is easy to
inadvertently create unusable SVG files) |
This graphics do not appear in any window while they are being drawn – SVG commands are written to a file and can be viewed in an SVG viewer after the plot is completed.
After the plot is completed, the function dev.off
must
be called to close the graphics device and flush all unwritten SVG
commands to the file.
