I am using the NLSY79 data (longitudinal data from the Bureau of labour stats in the US). The extractor exctracts this data in a "wide" format and I need to reshape it into a long format.
What I am doing right now is to do it in chuncks for each and evry variable that is 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)
