Hello, I have a large number of time series, which needs to be transformed by log or difference. Some of them are just processed by "level" (LV) without any transformation. For that purpose, I produce a text file (.csv or .xls) as follows: DLN DLNDLN LV LV LV....... How can I read the preceding strings so that I can easily access them, i.e., S[1]=DLN, S[2]=DLN, S[3]=DLN, S[4]=LV,S[5]=LV,S[6]=LV? I tried read.csv and read.table, but they don't work well. If I can access the string, then I will be able to write an "if" statement so that If the string is DLN, then take log and then difference. If the string is LV, then just keep it as it is.
