Please look at the help for boot, in particular what it says the form of
'statistic' should be. Possibly what you want is
corr.t <- function(data, ind) cor(data[ind,])[1,2]
nlaw appears to be a single-column matrix: that will not work either.

Hi R users,
I have one simple question but I really don't know why I can't get it work.
The data was adopted from Efron's An introduction to the bootstrap book.
nlaw
LSAT GPA
[1,] 576 3.39
[2,] 635 3.30
[3,] 558 2.81

[13,] 545 2.76
[14,] 572 2.88
[15,] 594 2.96
nlaw<-as.matrix(law[,-1])
corr.t<-function(data){
+ return(boot::corr(data))
+ }
law.boot<-boot(data=nlaw,statistic=corr.t,R=49)
Error in statistic(data, original, ...) : unused argument(s) (1:15)
many thanks for the help
