Hello all,
I'm trying to use zoo.read but can't figure out
how to deal with the time format. (example below)
would be nice if someone could help.
best regards,
Immanuel

f <- function(x) chron(paste(x[,1]),paste(x[,2]), format

z <- read.zoo(textConnection(L), index = 1:2, sep=",", header = TRUE,
FUN = f)
print(z)
