Bert, I tried readLines. It reads the data as is, but cant access individual columns. Still cant figure out how to accomplish this. An example would be of great help. PS: How do you indicate which fields are present in a record with less than the full number? - Via known delimiters for all fields. TIA Sachin Berton Gunter <[EMAIL PROTECTED]> wrote: How do you indicate which fields are present in a record with less than the full number? Via known delimiters for all fields? Via the order of values (fields are filled in order and only the last fields in a record can therefore be missing)?
If the former, see the "sep" parameter in read.table() and friends. If the latter, one way is to open the file as a connection and use readLines()(you would check how many values were present and fill in the NA's as needed).There may be better ways, though. ?connections will get you started. -- Bert Gunter Genentech Non-Clinical Statistics South San Francisco, CA "The business of the statistician is to catalyze the scientific learning process." - George E.
