Good morning!
I'm having trouble performing the analysis of a dot
pattern from the ArcGIS shapefiles.
I have the file "200milhas.shp" which is the map where the points are.
The points are in another file "todos_FeatureToPoint_Merge.shp"
I want to import this data set to R and do the analysis Kinhom. The
analysis should consider the map as my window. And need to
generate envelopes to test my hypothesis.
I imported the points:
> pontos =
readShapePoints("todos_FeatureTopoint_Merge.shp")
> class (pontos)
[1] "SpatialPointsDataFrame"
attr(,"package")
[1] "sp"
I converted the points to the format "ppp":
>
pppontos = as(pontos, "ppp")
>
class (pppontos)
[1]
"ppp"
When I type:
>
plot (pppontos)
Mensagens
de aviso perdidas:
1: In plot.ppp(pppontos) :
Some marks are
NA; corresponding points are omitted.
2: In plot.ppp(pppontos) :
There are too
many types to display every type as a different character
Points do not appear, but several characters of "marks".
How should I proceed?
Best regards,
Cleverson
