...s varying and then I merge the data together. This is taking a long time. my question is: How do I specify that there are multiple variables that are varying in reshape. Is there a way to do this? The idea is to have something like varying1, varying2,etc,... and each are assosiated with their own times1, times2. something like reshape(mydata, direction="long", varying1=varying1,varying2=varying2, varying3=varying3, split=list(regexp="[a-z][0-9]", include=TRUE), idvar="ID", times1=times1, times2=times2, times3=times3) Jean

Say you have a POSIX object that is in UTC. How do you change the values to another timezone? If I do this: times <- strptime(times, "%H:%M:%S") times1 <- as.POSIXct(times, tz="UTC") times2 <- as.POSIXct(times, tz="CDT6CST") times1 id UTC, but times2 is still UTC, not CTD. Why? Is the only was to change time zones to add seconds to POSIX objects? [[alternative HTML version deleted]]
