I'm sorry:
zscore<-function(x, y,...) {
lm<-lm( y ~ x , ...)
z <- coef(lm)/sqrt(diag(vcov(lm)))
return(z)
}
zscore(x, y, data=df)

HI,
Perhaps:
zscore<-function(x, y, data) {
lm<-lm( y ~ x , ...)
z <- coef(lm)/sqrt(diag(vcov(lm)))
return(z)
}

Hi,
I am writing a basic function to extract the z scores for some linear
regression coefficients:
zscore<-function( y, x) {
lm<-lm( y ~ x )
z <- coef(lm)/sqrt(diag(vcov(lm)))
return(z)
}
I would like to pass a dataframe to the function as a argument so the
function call changes from
zs
