Cohorts of Helianthemum squamatum seedlings
Description
Marked point patterns of two consecutive cohorts of seedlings of H. squamatum growing in a gypsophylous plant community in Central Spain. The datasets contains the locations of the seedlings marked with their heigth. Both the coordinates and the heigth of the seedlings are given in cm.
Usage
data(seedlings1)
data(seedlings2)
Format
seedlings1 and seedlings2 are objects of class "ppp" representing the point pattern of seedling locations marked by their heights. See ppp.object
for details of the format.
