R-users, Attached is the file (SR_use2.txt) I'd like to include and includes column headers. nat_est is the response variable and is the number of species at a particular point. The other variables are the explanatory vars (vark, var2, var1, UK, U2, U1, GK, G2, G1, PK, P2, P1).
Here is Walsh's sample code for hier.part: data(urbanwq) env <- urbanwq[,2,8] hier.part(urbanwq$lec, env, fam="gaussian", gof="Rssqu") The code I wrote is library(hier.part) SRUSE<- read.table("F:\\GEORGIA\\species_richness\\SR_use2.txt", sep=" ", header = TRUE, row.names = 1) TEMP<- SRUSE[2:13] hier.part(SRUSE$nat_est,TEMP, family="NegBin", gof="logLik", barplot= TRUE) So far this doesn't work and I'd really appreciate some help. While I have your ears, what books would one make for the clueless? Many thanks, Jeff PS. nat_est is the estimated number of species (species richness). Around each of the sampling points I calculated the % of different types of cover (pine, hardwoods, number of different covers) in three scales around the sampling points (1000, 200, and 100 m). What I'm hoping to do with the analysis is to find the best scales and parameters that best predicts species richness. . **************************************** Jeffrey A.
