Ok. read.table and count.fields don't have identical defaults.

R> args(count.fields)
function (file, sep = "", quote = "", skip = 0)

R> args(read.table)
function (file, header = FALSE, sep = "", quote = "\"'", dec = ".",
    row.names, col.names, as.is = FALSE, na.strings = "NA", skip = 0)


So if count.fields likes your data but read.table doesn't, you probably
want

 read.table("Consult/krasdata",sep="\t",quote="")


Please don't use Base64 encoding in attached files -- it was quite hard to
find a program to decode it, and it's really intended for sending binary
files.  Use plain text, and if your mailer insists on encoding attachments
then just cut and paste the output into the message.
