emap: Add blank map

In JohnCoene/echarts: EChart htmlwidget

Description

Setup map plot.

Usage

emap(p, name = NULL, mapType = "world", clickable = TRUE, z = 2,
  zlevel = 0, selectedMode = NULL, hoverable = FALSE,
  dataRangeHoverLink = TRUE, mapLocation = list(x = "center", y = "center"),
  mapValueCalculation = "sum", mapValuePrecision = 0,
  showLegendSymbol = TRUE, roam = FALSE, scaleLimit = NULL,
  nameMap = NULL, textFixed = NULL, ...)

emap_(p, name = NULL, mapType = "world", clickable = TRUE, z = 2,
  zlevel = 0, selectedMode = NULL, hoverable = FALSE,
  dataRangeHoverLink = TRUE, mapLocation = list(x = "center", y = "center"),
  mapValueCalculation = "sum", mapValuePrecision = 0,
  showLegendSymbol = TRUE, roam = FALSE, scaleLimit = NULL,
  nameMap = NULL, textFixed = NULL, ...)

Arguments

p	an echart object.
name	name of serie.
mapType	type of map, see examples.
clickable	whether elements are clickable.
z, zlevel	first and second grade cascading control, the higher z the closer to the top.
selectedMode	whether items can be selected.
hoverable	whether elements are hoverable.
dataRangeHoverLink	enables dataRange hover link to the chart.
mapLocation	x and y location of map on canvas, takes top, bottom, left, right, center.
mapValueCalculation	takes sum or average.
mapValuePrecision	decimal precision.
showLegendSymbol	whether to show symbol on legend.
roam	enables zoom and drag.
scaleLimit	controls drag and zoom limits.
nameMap	custom name mapping.
textFixed	fixed text location for a region.
...	any other options to pass to map serie.
