Can you be more explicit about your problem?
Michael, Data frame contains water chemistry data; site, date, parameter, value. The column names after dcast() are, for example, alk_quant, ph_quant, tds_quant. I wanted to remove the '_quant' from each column header. Using names() with a string vector of the new names did not work, so I specified each one and names() made the changes.
