#this is a subset of a larger data frame and I am okay with subsetting it as there are redundant time stamps, but I would like to create a zoo object out of this and I am having a hard #time figuring out how to do this the date structure is year and then month

x <- structure(list(Yearmonth = structure(c(12L, 24L, 1L, 13L, 14L,
3L, 15L, 4L, 16L, 5L, 17L, 6L, 18L, 7L, 19L, 8L, 20L, 9L, 21L,
10L, 22L, 11L, 23L), .Label = c("2006-02", "2006-03", "2006-04",

"2006-05", "2006-06", "2006-07", "2006-08", "2006-09", "2006-10",
"2006-11", "2006-12", "2007-01", "2007-02", "2007-03", "2007-04",
"2007-05", "2007-06", "2007-07", "2007-08", "2007-09", "2007-10",
"2007-11", "2007-12", "2008-01"), class = "factor"), Month = c(1L,
1L, 2L, 2L, 3L, 4L, 4L, 5L, 5L, 6L, 6L, 7L, 7L, 8L, 8L, 9L, 9L, 10L, 10L, 11L, 11L, 12L, 12L)), .Names = c("Yearmonth", "Month" ), class = "data.frame", row.names = c(NA, 23L))

#thanks Stephen
