Hi R users,
I just play with a small data set (from SAS) by using the boot with glm. But
I don't know what I did wrong. Would someone please give me a
hint?> require(boot)
> carc<-read.table(file="C:\\Documents and
> Settings\\admin\\Desktop\\drug.txt",header=T)
> carc
n cc car age
1 500 42 S 1
2 1200 37 M 1
3 100 1 L 1
4 400 101 S 2
5 500 73 M 2
6 300 14 L 2> dfd<-function(d,i){
+ d<-carc[i,]
+ car.glm<- glm(cc ~ car+age+offset(log(n)), family=poisson(link
"log"), data=d)
+ coefficients(car.glm)
+ }>
> car.boot=boot(carc,dfd,9999)
Error in t.star[r, ] <- statistic(data, i[r, ], ...) :
number of items to replace is not a multiple of replacement length
Many Thanks
