...ro), nothing happens. Does anyone have an explanation, or any suggestions as to how to run an R program from within an Excel macro? (PS: I know about RExcel, can't quite get it to install correctly.) Much appreciated.

...ow if any R package has a function that will conduct Hollander's test of bivariate symmetry? (Hollander, Biometrika, 1971) Either the exact test or an asymptotic version would be sufficient for my purposes. Thanks.

...function(y) {x + y}; w <- function(x){q(x)}; w(2); According to the discussion of Scope on page 46, it seems to me that R will interpret the free variable x in q as the parameter x in w, and so will give w(2) = 2+2.

...lt;<- x+1; return(q(x))} else return(x)} If x < 1, this should add 1 to x and go back to the beginning of the if expression, and the final result should be 2. So q(0) should return 2. But it returns an error message. Joe Boyer Statistical Sciences Renaissance Bldg 510, 3233-D Mail Stop RN0320 8-275-3661 cell: (610) 209-8531 [[alternative HTML version deleted]]

...x, wghts ){ lm(y~x, weights = wghts) } prac(y=y, x=x, wghts = rep(1, 10)) I would be grateful for an explanation of why the first program does not work. It seems to me like they should both give the same result.
