eMarkPoint: Create an markpoint using the ECharts(version:3.2.2) library
In cosname/recharts: An R Interface to ECharts

This function creates an HTML widget to display matrix, data.frame and factor array, using the JavaScript library ECharts3.

eMarkPoint(chart, dat = NULL, xvar = NULL, yvar = NULL,
  series = NULL, type = NULL, valueIndex = 0, seriesIndex = NULL,
  symbol = "pin", symbolSize = 50, symbolRotate = NULL,
  symbolOffset = c(0, 0), silent = TRUE, label = NULL,
  itemStyle = NULL)

`chart`	a recharts object
`dat`	a data object (a matrix, a data frame or a factor array)
`xvar, yvar`	objects of class "formula" (or one that can be coerced to that class): x,y coordinates of the given data.frame colnames, e.g. `xvar = ~xAxisName`; `yvar = ~yAxisName`. xvar, yvar only needed for the data.frame data input.
`series`	an "formula" object: Associates the levels of variable with symbol color, e.g. `series = ~groupName`
`type`	default is NULL,
`valueIndex`	default is 0,
`seriesIndex`	default is NULL,
`symbol`	default is 'pin',
`symbolSize`	default is 50,
`symbolRotate`	default is NULL,
`symbolOffset`	default is c(0,0),
`silent`	default is FALSE,
`label`	default is NULL,
`itemStyle`	default is NULL
`size`	an array of html widget width and height(either numeric pixels or percentage could be accepted): e.g. size = c(1024, 768).

dat <- cut(rnorm(1000), -4:4)
chart = eLine(dat)
eMarkPoint(chart, type=c('max','min'),valueIndex = 1)
eMarkPoint(chart, dat = data.frame(2:3,rep(200,2)),
           type=c('max','min'),valueIndex = 1)
