Thanks for the response. I could resolve the problem. The problem, as

the melt() function call is syntactically correct.
The unmodifed data frame is organized this way:
head(tds.anal)
site sampdate param quant
1UDS-O 2006-12-06 TDS 10800
4 STC-FS 1996-06-14 Cond 280

This might be an easier method:
suppose your data is in MAT
t(apply(MAT, 1, function(v) eigen(matrix(v, 2))$values))
Your problem is that return() automatically returns the output and
ceases function execution as soon as its hit.

Thanks Dimitris,
but I would like to bind the result on the dataframe, so the length
should be equal to nrow(df1).
BTW, sorry for the example, it wasn't very clear, next try:

Hi,
Yea Linux! I think you are missing a library file (libgfortran.so.1),
you can use locate to try and find the so file, in bash type:
locate libgfortran
Now three things can happen:
- It doesn't find anything, than you need to install an additional
gfortran package. This is often called libgfo

What is the best way to get a time series of daily stock price observations

The time series are daily but there are spaces for w/e's and holidays etc.
So I am not sure a ts object will be suitable but I am not sure what I
should use?
What ever package you recemmned

In your loop, you assign, for example, pv twice
pv=w$p.value # pv is scalar
pv[i]= w[2] # pv is a vector
give an example for the point
pv=1
pv[5]=2

This may not be what you want.
