Manipulations of a data frame or list -- rename or re-assign?
Hello, Maybe you could keep the original, and reuse only one (another) object for the intermidiate steps. That's how I would do it. Hope this helps, Rui Barradas Em 03-08-2013 12:27, Ben Harrison escreveu:
If I am to do a lot of pre-processing operations on some data, comprising many steps such as: -- despike a set of signals -- smooth a set of signals -- filter -- subset -- impute missing values etc... Should I be assigning the result of each operation to a new object, and then destroying the old one, or is it fine to reassign the object to itself? df <- sapply(df, someFunction, arg=10) OR df.new <- sapply(df, someFunction, arg=10) Ben University of Melbourne
