Hi Andreas,

Assuming you are using read.table(), try setting the argument:
stringsAsFactors = FALSE

Also consider what about the Excel file is making R default to a
factor rather than numerical?  There may be a nonstandard
reprsentation of missing data (e.g., "."), which could also be
specified to read.table()

For more info, see the documentation for ?read.table

HTH,

Josh
