[R] A question about data frame

[Phil Spector]

Gang -
    It sounds like you want your character variables to
be stored as character values, not factor values.  If that's
the case, use

df = data.frame(n, s,stringsAsFactors=FALSE)

If you want them to be factors, but not to display as factors,
others have provided usable solutions.
