## Function MAPI_Plot2

### Description

Plot a MAPI analysis result with ggplot

### Usage

    MAPI_Plot2(
      resu,
      tails = NULL,
      samples = NULL,
      pal = c("#994000", "#CC5800", "#FF8F33", "#FFAD66", "#FFCA99", "#FFE6CC", "#FBFBFB",
        "#CCFDFF", "#99F8FF", "#66F0FF", "#33E4FF", "#00AACC", "#007A99"),
      shades = 20,
      main = "",
      upper = TRUE,
      lower = TRUE,
      upper.border = "black",
      lower.border = "gray"
    )

### Arguments

`resu` | A spatial object of class 'sf' resulting from a MAPI analysis done using `MAPI_RunAuto` or `MAPI_RunOnGrid`.
`tails` | An optional spatial object of class 'sf' resulting from the post-process with `MAPI_Tails` of a MAPI analysis result. Default = NULL (no tails shown).
`samples` | A data.frame with names and geographical coordinates of samples. Column names must be: 'ind', 'x', 'y'. Optional column 'errRad' with an error radius for sample locations (eg. GPS uncertainty). Coordinates must be projected (not latitude/longitude).
`pal` | A color ramp, eg. from RColorBrewer (default: orange > light gray > blue)
`shades` | Number of breaks for the color ramp (default 20)
`main` | Plot title (none by default)
`upper` | If TRUE and tails is not NULL, upper-tail significant areas are plotted. TRUE by default.
`lower` | If TRUE and tails is not NULL, lower-tail significant areas are plotted. TRUE by default.
`upper.border` | Border color of the upper-tail significant area. "black" by default.
`lower.border` | Border color of the lower-tail significant area. "gray" by default.

### Value

Returns the ggplot object.

### Examples

    ## Not run:
    library(ggplot2)
    data("metric")
    data("samples")
    resu <- MAPI_RunAuto(samples, metric, crs=3857, nbPermuts = 1000)
    tails <- MAPI_Tails(resu)
    pl <- MAPI_Plot2(resu, tails=tails, samples=samples)
    # Save to image
    ggsave("mapiPlotOutput.png", plot=pl)
