addDefault {sendplot} | R Documentation |
The default region in an html image map is any part of the figure not already specified with a different region (i.e. rect, circle, poly). This function adds tool-tip information to the default region.
addDefault(Splot, data=NA, data.labels=NA, links=NA, links.labels=NA, asLink=NA, font.type="Helvetica", font.color="black", font.size="12", bg.color='#D6E3F6', returnVl=TRUE, saveFlag=FALSE, saveName="Splot.RData")
Splot |
An Object of the class Splot |
data |
character vector containing data to be displayed in tool-tip |
data.labels |
names descripting data vector |
links |
character vector containing complete web address for hyperlinks within tool-tip |
links.labels |
names describing links vector |
asLink |
complete web address for area to be treated as hyperlink |
font.type |
font type for tool-tip. Currently support fonts are Arial, Helvetica,and sans-serif |
font.color |
font color for tool-tip |
font.size |
font size in tool-tip |
bg.color |
background color of tool-tip |
returnVl |
logical indicating if Splot object should be returned |
saveFlag |
logical indicating if Splot object should be saved to a file |
saveName |
if saveFlag, path and file name to save object |
This function takes in data and links vectors, and converts into proper syntax for tool-tip. It also sets up default tool-tip display regarding font color, size, and type, as well as background color.
The Splot object is updated to include a Default.Obj containing vectors in proper syntax and tool-tip display information.
There can only be one default for a given layout of figures. If this is run more than once it will override previous calls.
