Check Stuff

Auxiliary (dot) functions to check various attributes of PBmapping objects.

.checkClipLimits(limits)
.checkProjection(projectionPlot, projectionPoly)
.checkRDeps(caller="unspecified", requires=NULL)

Arguments

• limits: numeric -- 4-element vector of limits for 'X' and 'Y'
• projectionPlot: character -- projection of the currently plotted map
• projectionPoly: character -- projection of the PolySet, presumably to add to map
• caller: character -- a function name
• requires: character -- a vector of package names

.checkClipLimits : nada; just a limit checker

.checkProjection : nada; just a projection checker
