tprintf("Range=%d\n", max + 1 - min);
tprintf("Mean= %.2f\n", mean()); tprintf("SD= %.2f\n", sd());
}
is called in the same file here:
void STATS::print() const { //...}
generic 'print' name, frequency of invocations of this and unfamiliar
w/tesseract organization make it tough to see where the call can be
disabled atm.
Any suggestions/pointers are much appreciated.
