I have a marked point pattern RDS object that contains information on the location of 5 different species of algae. I want to be able to create 5 new objects, each containing just the data for an individual species, not all five. The different species are stored under "marks" as a factor with 5 levels, one for each species.
algae_sp1 <- algae$marks == "species1"
But when I plot that object I don't get points. I'm really new to using spatial data in R. Thanks for the help.
