loaded via a namespace (and not attached):
[1] grid_2.8.0 lattice_0.17-15
I have a large data set that I have been reading in the same way
read.production() from the StreamMetabolism package and it has worked
in the past without a hitch
##########code provided#############
read.production <- function(data) { read.zoo(data, sep = ",", FUN =
fmt.chron, header = TRUE)}
fmt.chron <- function (x) {chron(sub(" .*", "", x), gsub(".* (.*)",
"\\1:00", x))}
this is the first time that I have used this data since the upgrade to
2.8 and it is taking longer to preform operations. What can I do to
help diagnose the problem. I know this is not reproducible, but I
don't know without sharing the entire data set how to do that.
Thanks in advance
