Recover the internal data arrays

Synopsis
getdata()

Returns
Glish record

Description

This function returns a Glish record holding the internal data. The record has fields 'x', 'y', 'xerr', 'yerr' and 'mask' holding the obvious quantities. The data error fields may be unset if no data errors were given. However, the mask field will always be filled in. If you gave no mask, the mask field will hold an all T (good) vector.

Example

- include 'functionfitter.g'
- ff := functionfitter()
- x := 1:10
- y := 2 + 3*x
- ff.setdata (x, y)
- r := ff.getdata()
- print r
[x=[1 2 3 4 5 6 7 8 9 10] , y=[5 8 11 14 17 20 23 26 29 32] , 
 xerr=[i_am_unset=i_am_unset], yerr=[i_am_unset=i_am_unset], 
 mask=[T T T T T T T T T T] ]
