It is important that you say that you are are using package vrtest, and how
your calls look in detail. Does the example below work?


data(exrates)
y <- exrates$ca                                 # read Canadian exchange
rate
nob <- length(y)
r <- log(y[2:nob])-log(y[1:(nob-1)])           # log return calculation
kvec <- c(2,5,10)
Lo.Mac(r,kvec)  # will display (or better "print")

 f = Lo.Mac(r,kvec) # this will not display anything, which is mostly the
case for similar function
f # this will display something
print(f) # same result
