S'ALG_DESC'
p1
VThis algorithm creates a graph that demonstrates the dependency of the intensity of the point process on the value of covariate. In this algorithm the covariate is the distance to the certain objects. The functionality is based on 'rhohat' function of the 'spatstat' package. \u000a\u000aR dependencies: library "maptools", "spatstat" and "rpanel".

p4
sS'Layer'
p5
VThe point process which distribution will be investigated.
p6
sS'Covariate_name'
p7
VThis field is mandatory. Enter the name of the covariate. It will appear at the graph.
p8
sS'Legend_position'
p9
VThis field defines the position of the legend at the graph. 'float' means that the legend will be placed at the position that would not overlap the graph itself (or will try at least). Other options are: 'topleft', 'topright', 'bottomleft', 'bottomright'.
p10
sS'x_label'
p11
VOptional label for the X axis. Note that units at the X axis will be the same as in the input layers.
p12
sS'RPLOTS'
p13
VThe empirical graph of the dependency of the intensity of the point process on the distance to the given objects.
