[R] help getting data in correct format

[Benjamin B.]

When I try to read data from excel, I save it in csv-format and read the files via:

fileData  <-read.csv(fkFileName, header = fkHasHeader, stringsAsFactors=FALSE, sep=fkSep)

where fkSep is depending on your localization of excel (I think).
For some columns that don’t get the correct data format on import I use

fileData[,col]   <-as.<dataType>(fileData[,col])

Maybe you can use read.csv2 if you have a german (or european) excel.
