help with hier.part
Hi although I do not know anything about hier.part package I try few comments - see posting guide as it suggest to try to present a toy example which shows your problem - are there some error messages or the result is not as you expect? - what is TEMP - seems to me that you need to define it before hier.part() function and you did it but I am not sure if it contained what it should contain - usually when something "does not work" means I made a mistake and I have to bore deeper to to syntax and man pages of a function. I swear that reading all posibble sources of information is worth the time if you really want to use R. HTH Petr

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. .
