Hi,

Code: 
$f-measure  = (2 * $recall * $precision) / ($recall + $precision);

gives me the following error message:
Can't modify substraction (-) in scalar assignment at line (the one above) near ");"

This is insane: why doens;t this work ?!

it's interpreting is as $f minus measure. Try using $f_measure (with an underscore) instead.

Thank you,

How silly on my part not to see that !
I guess it is time for a break.
