[R-SIG-Finance] timeDate class query

[Ian Seow]

Hi Yohan thanks for your reply. Are you referring to version 270.75
for fCalendar? This is the latest version I could find and it is the
version I am currently using. I must be missing something, because
when I try length(timeCalendar( ) ) I get the following error:

> test=timeCalendar(m = c(9, 1, 8, 2), d = c(28, 15, 30, 9),
+                 y = c(1989, 2001, 2004, 1990), FinCenter = "GMT")

> test
GMT
[1] [1989-09-28] [2001-01-15] [2004-08-30] [1990-02-09]

> length(test)
Error in prod(x at Dim) : no slot of name "Dim" for this object of class "timeDate"
