Hi, I have doubts in using subset command. I have a list of, lets say, 15 species and I want to make a subset with only 2 of them. I’m the command data2 <- subset(data1, species=="sp1"|species=="sp2")
Nevertheless, when I ask for the summary (summary(data2)) the others species names still apearing. Also I tried data2<-data1(data1$species %in% c("sp1","sp2")),] But I got the same result. How can I get a “clean” subset? Thanks for any help. Best regards.
