Hi everyone
I am new to the list and read all the instructions, hope i get it right.
I have the following linear model:
model_sqrt<-lm(sqrt(mortality)~richness
+Acer_davidii+Ailanthus_altissima+Alniphyllum_fortunei
+Betula_luminifera+Castanea_henryi+Castanopsis_carlesii
+Castanopsis_eyrei+Castanopsis_fargesii+Castanopsis_sclerophylla
+Celtis_biondii+Choerospondias_axillaris+Cinamomum_camphora
+Cyclobalanopsis_glauca+Cyclobalanopsis_myrsinifolia+Diospyros_glaucifolia
+Elaeocarpus_chinensis+Elaeocarpus_glabripetalus+Elaeocarpus_japonicus
+Idesia_polycarpa+Koelreuteria_bipinnata+Liquidambar_formosana
+Lithocarpus_glaber+Machilus_grijsii+Machilus_leptophylla
+Machilus_thunbergii+Manglietia_yuyuanensis+Melia_azedarach+Meliosma_flexuosa
+Nyssa_sinensis+Phoebe_bournei+Quercus_acutissima+Quercus_fabri
+Quercus_phillyreoides+Quercus_serrata+Rhus_chinensis+Sapindus_mukorossi
+Sapium_discolor+Sapium_sebiferum+Schima_superba
+community
,weights=wei)
Where everything from Acer_davidii to Schima_superba are plant species. Since
the order of the plant species matters in my case, I want to repeatedly fit the
model so that every species is in the first place, that is after the richness
term, once.
I am looking for a way so that I don't have to do this by hand. I already
checked combn with as.formula and paste, but I couldn't get it right.
I'd be very grateful for any help.
Thanks
David
