[R] Trouble when I call a function within another

[bbouling]

Yep, sorry I forgot it :wistle:

so the data are data frames with dim(8,1000) called DATA.ValX and DATA.ValY
(part of the files attached as a xls file)

http://www.nabble.com/file/p18826528/ValX.xls ValX.xls 
http://www.nabble.com/file/p18826528/ValY.xls ValY.xls 

When I call the function "Test" to determine the formula, nls returns an
error; there are no initial values for x and y whereas without the function
"Test" and directly a formula; no error occurred in nls with the same DATA.
