hist.SpatialPixelsDataFrame function

Histograms of Mapped Variables

hist.SpatialPixelsDataFrame performs histograms of the variables mapped in objects of class SpatialPixelsDataFrame.

## S3 method for class 'SpatialPixelsDataFrame'
hist(x, type = c("h", "l", "b"),
                                      adjust = 1, col, border,
                                      lwd = 1, ...)

Arguments

• x: a raster map of class SpatialPixelsDataFrame

• type: what type of plot should be drawn. Possible types are:

  • "h" for histograms,

  • "l" for kernel density estimates (see ?density).

  • "b" for both histograms and kernel density estimates (see ?density).

  By default, type = "h" is used. If type = "l" is used, the position of the mean of each distribution is indicated by dotted lines

• adjust: if type = "l", a parameter used to control the bandwidth of the density estimate (see ?density)

• col: color for the histogram

• border: color for the border of the histogram

• lwd: if type = "l", line width for the density estimate

• ...: further arguments passed to or from other methods
