[R] read.zoo question

[Gabor Grothendieck]

Try

read.zoo(myfile, sep = ",", FUN = as.POSIXct)

or

to.chron <- function(x) {
	s <- do.call(rbind, strsplit(format(x), " "))
	chron(dates(s[,1], format = "Y-M-D"), times(s[,2]))
}
read.zoo(myfile, sep = ",", FUN = to.chron)

depending on which class you want.
