I have a simple question. I am trying to load data into a zoo object. I have
the data in CSV format as follows
SYMBOL DATE TIME PRICE
XX YYYYMMDD HH:MM:SS n.nn
and there are multiple symbols in this one data frame.
My question is, do I need to merge DATE and TIME before loading them or can
I specify multiple index.column or index.name fields?
index.column in read.zoo is a single column only
you can either merge in your CVS format, simplifying things in R, or use
read.table to get the data into R and then merge your index columns when you
call as.zoo.
