Overloads the default plot for objects of class 'geomerge'.
# S3 method for geomerge
plot(x, ...)
object of class geomerge.

Karsten Donnay and Andrew M. Linke.
Returns a series of maps that visualizes numeric variables produced by geomerge. It returns a map for each unique numeric variable including first order spatially and temporally lagged values if spat.lag=TRUE and time.lag=TRUE when running geomerge. For spatial panels, the function by default returns values for the last period.
Five optional arguments that are specific to this plotting function can be provided. The first is period, a numeric input that allows to specify a specific period to be plotted. inputs must be a sequence of character strings specifying select variables to be plotted only. These have to have been merged (with the same name) in geomerge. time.lag and spat.lag override the boolean values parsed automatically from the result of geomerge. They are mainly meant to switch off plotting of spatial and temporal lags as they are ignored if these lags were not generated in the first place. The last argument is ncol, a numeric input, which allows to specify the width of the panel of plotted maps. By default, always 2 maps are shown side-by-side.
