Hi,

I have a two Colum matrix ( I named it holder) as shown bellow. It seems
to be three columns, but the first column contains the row names.

I am trying to fill all  NAs by linear interpolation the known values in
the matrix. I tried using the interpNA function, but I get an error
message:

> interpNA(holder, method = "linear")
Error in approx(idx, x[idx], 1:n, method = method, f = f) : 
  need at least two non-NA values to interpolate
In addition: Warning message:
In xy.coords(x, y) : NAs introduced by coercion
> 


I was wondering if some one could recommend another function to get the
interpolated values?

Thanks,

Jorge
