## S3 method for class 'kinmap'
plot(x, param, zlim=NULL, xlab="L", ylab="M", zlab=NULL,
                   color.table=heat.colors(100), logz=FALSE, ...)

`x`	an object of class `kinmap` created with `fit.cube`. A `kinmap` is a list that contains at least the elements `L` and `M` as well as the measurement specified by `param`.
`param`	a character string specifying the measurement to be plotted. This has to correspond to a column name present in `x`.
`zlim`	the minimum and maximum 'z' values for which colors should be plotted, defaulting to the range of the finite values of 'z'.
`xlab, ylab`	each a character string giving the labels for the x and y axis. Defaults are "L" and "M".
`zlab`	the label for the colour bar. This defaults to `param`. For parameters `sigma`, `v` and `gof`, special labels using Greek characters are hard-coded.
`color.table`	The colour table to be used. Defaults to `heat.colors(100)`
`logz`	Logical. If `TRUE`, then the logarithm of the measurement is plotted. This is useful for surface brightness. Note that no checks are performed whether the measurement is positive everywhere!
`...`	graphical parameters for 'plot' may also be passed as arguments to this function, as can the plot aspect ratio 'asp' and 'axes' (see 'plot.window'). Note that these parameters only apply to the main plot, not the colour bar.
