sendplot (version 4.0.0)

imagesend: INTERACTIVE IMAGE

Description

This function is a wrapper to sendplot that will create a single interactive image

Usage

imagesend(plot.call, 
           x.pos,
           y.pos,
           xy.type,
           plot.extras = NA,
           mai.mat=NA, mai.prc=FALSE,
           xy.labels=NA,
           image.size="800x1100",
           spot.radius = 5,
           fname.root="Splot",
           dir="./",
           window.size = "800x1100", 
           ...)

Arguments

plot.call
character vector containing single plot call
x.pos
vector of x locations for interactive points
y.pos
vector of y locations for interactive points
xy.type
Indication of how the xpos and ypos values should be treated.Current options are "image.midpoint","image.boundaries", or "image.box".See details or vignette.
plot.extras
List of additional plotting calls that should be executed for the plot.
mai.mat
1 x 4 matrix of values to be passed in for each plots par mai. n is equal to the length of plot.calls. If NA, uses default margins.
mai.prc
logical indicating if mai mat values are percentages or hard coded values. If mai.proc is T, indicates percentage.
xy.labels
list of matricies. All matricies should be of n x m where n is the length of y and m is the length of x when xy.type is "image.midpoint". All matricies should be of n x m where n is the length of y -1 and m is the length of x - 1 when xy.type
image.size
character indicating size of device.
spot.radius
radius of circle in pixels indicating area that will be interactive around the center of graphed points
fname.root
Base name to use for all files created.
dir
directory path to where files should be created. Default creates files in working directory
window.size
size of the html window
...
additional arguments to the makeImap function

Value

  • Creates a static and interactive image

Details

This function is a wrapper for the sendplot function to create a single interacive image. See initSplot, makeImap, and makeSplot for more information. Users are encouraged to read the package vignette which includes a detailed discussion of all function arguments as well as several useful examples.
