Details

These functions extract or modify the marks of a Dtable.

`marks<-.wmppp()` just calls `marks<-.ppp()` and keeps the class of the wmppp object. The conformity of the marks with the definition of the class "wmppp", i.e. a dataframe with columns "PointType" and "PointWeight" of the same length as the number of points, is not checked.

Examples

# A Dtable containing two points
Dmatrix <- matrix(c(0,1,1,0), nrow=2)
PointType <- c("Type1", "Type2")
PointWeight <- c(2,3)
X <- Dtable(Dmatrix, PointType, PointWeight)
# Extract the marks
marks(X)
