Given
Y_t = a + b X_t
by first-differencing you get:
Y_t - Y_t-1 = b ( X_t - X_t-1)
Alright, that makes

Hi,
not sure if it's a bug, but looks at least like some inconsistency:
eval regsub("ha", "a", "\n") # works
eval regsub("ha", "a", sprintf("\"")) # works
eval regsub("ha", "a", "\"") # fails
I know that plain literal strings in gretl aren't made for escape
sequences, but the regsub doc

This would be useful if the input array actually holds textual
representations of numbers, which can then be processed with sscanf.
OK sorry, just found out that sscanf now (since 2019c) also accepts
string arrays.
Perhaps some more flexibility
