I am getting an error when trying to use melt() on a dataframe containing Dates
- by Dan
I'd like to melt the dataframe so that in one column i have dates in a second i have username as the variable and finally the value.
I'm getting this error:
Error in as.Date.numeric(value) : 'origin' must be supplied
and while I understand the error I'm not exactly sure how to get around it.
A small sample of the data is:
structure(list(created_at = structure(c(14007, 14008, 14009,
14010, 14011, 14012), class = "Date"), benjamin = c(16, 0, 0,
0, 0, 0), byron = c(0, 0, 0, 0, 0, 0), cameronc = c(0, 0, 0,
0, 0, 0), daniel = c(0, 0, 0, 0, 0, 0), djdiaz = c(0, 0, 0, 0,
0, 0), gene = c(16, 77, 64, 38, 72, 36), joel = c(0, 0, 0, 0,
0, 2), kerem = c(0, 0, 0, 0, 0, 0), sophia = c(0, 0, 0, 0, 0,
0), SuperMoonMan = c(0, 0, 0, 0, 0, 0)), .Names = c("created_at",
"benjamin", "byron", "cameronc", "daniel", "djdiaz", "gene",
"joel", "kerem", "sophia", "SuperMoonMan"), row.names = c(NA,
6L), class = c("cast_df", "data.frame"))
Thanks for your help.
