[Rd] cannot wrap lmekin function

I had a problem with the lmekin() in Kinship package: lmekin() can not be wrapped into another function

For example:

#creat an example dataset

xx<-rnorm(100);yy<-rnorm(100) ;id<-1:100; test.dat<-as.data.frame(cbind(xx,yy,id)) ; rm(xx,yy,id) a<-bdsmatrix(rep(10,10),rep(block,10),dimnames=list(c(1:100),c(1:100)))

#this works: call lmekin directly


#this doesn't work: wrap lmekin into another function



Error in eval(expr, envir, enclos) : Object "y" not found

I did line by line debug within lmekin(). I found the problem was from line #25
m <- eval(m, sys.parent())

Here is the print(m) result before this line [1] model.frame(data = data, na.action = na.omit, formula = y ~ x +z)

It seems data cannot be passed to the arguments when lmekin() is wrapped into another function.
Can anyone help me to figure a fix?

Thanks a lot!
