G'Day,
I'm a little confused why the c function has the followng effect on
classes - is this a feature ? My workround [ class(cc) <- c("POSIXt",
"POSIXct") ] seems to do the job.
It's a legacy
c.POSIXct <- function(..., recursive=FALSE)
structure(c(unlist(lapply(list(...), unclass))),
class=c("POSIXt","POSIXct"))
does the job.
Speaking of the devil... Is there any reason as.POSIXct shouldn't work on numeric data?
as.POSIXct(0)
Error in as.POSIXct.default(0) : Don't know how to convert `0' to class "POSIXct"
structure(0,class=c("POSIXt","POSIXct"))

(Discovered by trying
c.POSIXct <- function(..., recursive=FALSE)
as.POSIXct(c(unlist(lapply(list(...), unclass))))
)
