Value
This is an rpanel function for visual choice of lambda(s), the output is a variable, varname, with the density *per unit time*
the variable varname can be fed to the function ginhomAverage or KinhomAverage as the argument density (see for example ?ginhomAverage), or into the
function thetaEst as the argument spatial.intensity.
Details
A tool for the visual estimation of lambda(s) via a 2 dimensional smoothing of the case locations. For parameter estimation, the alternative is
to estimate lambda(s) by some other means, convert it into a spatialAtRisk object and then into a pixel image object using the build in coercion
methods, this im object can then be fed to ginhomAverage, KinhomAverage or thetaEst for instance.
