Hi All,
I did a google search and could not find the answer. Thus I post this
message. I found runmax only work for positive numbers.
x = rep(-1,10)
runmax(x,3)
x = rep(0, 10)
runmax(x,3)
for 32-bit R, i got very small numbers: 2.121996e-314
for 64-bit R, i got NaN.
Is it a bug in runmax? or should this be included in the documentation that
runmax only for positive numbers?
however, we do have a workaround -- runmin works, thus we can do y =
-runmin(-x,3).
Thanks.
