Thanks, Erik. I will try your code soon.
I did this first:

Dear Erik and Wacek,
I would request that you stop working on my problem. I had the second column
deleted
and the problem is gone. I don't know why but apparently the second column
somehow
interfered with the third column such that the third column is regarded as
'factor' not
'numeric'.

See ?Extract
And if I try to use as.ma
It is:

And if I try to use as.matrix(read.table()), I got:

Hi Wacek,
Yes, data is data frame not a matrix.
is.numeric(data[3])
[1] FALSE
what is class(data[3])
But I looked at the column 3 and it looks okay though. There are few NAs and
I did find
anything strange.
Any suggestions?
Thanks,

looks like you have a data frame, not a matrix
