[R] time difference error

[jim holtman]

I think the error message says it all.  "fix" can not handle the data
type of tdiff:

> tdiff <-structure(c(168, NA, NA, 165, 175, 140, 191, 195, 130, 160, 135,
+  165, 330, 178, 141, NA, 119, 90, 70, 99, 115, 70, 65, 90, 90, 65, 90, 75,
+  85, 93, 52, 75, 60, 90, 105, 70, 65, 60, 85, 110, 65, 60, 98, 62, 71, 61, 41,
+  80, 67, 83, 72, 73),
+  tzone = "", units = "mins", class = "difftime")
> tdiff

If you want to look at it, use "View".
