attributeTree | R Documentation |
Function to attribute the trees on each subplot, the trees that are at the exterior of the subplot will be marked as NA
attributeTree(xy, plot, coordAbs)
xy |
The coordinates of the trees for each plot |
plot |
The label of the plot (same length as the number of rows of |
coordAbs |
Output of the function |
A vector with the code of the subplot for each trees, the code will be plot_X_Y
. X
and Y
are the coordinate
where the tree is inside the plot in regards to the corresponding subplot.
