Summarizes multi-band raster data within each element of a SpatialPolygons object.

1	analyseTS(x, y, out.plot = NULL)

`x`	Object of class data.frame.
`y`	Vector of class character or numeric with a length equal to the number of rows in x.
`out.plot`	Specifies the data path where plots should be stored.

For each unique value in y, the function will select the rows in x that correspond to it and estimate the median, Median Absolute Deviation (MAD), minimum, maximum, mean and standard deviation for each column. Then, the function will build a plot showing the median and draw a buffer that expresses the minimum and maximum. The final output is a list consisting of:

y.statistics - Median, minimum and maximum values for each column in x over each unique class in y.
plots - List of line plots for each unique element in y.

If out.plot is set, the function will save each plot as 10x10 cm PNG files within the specified path.

A SpatialPointsDataDrame with the coordinate pairs for each of the sampled pixels.
