Hi, noobie! ;-)
If the resistor let the smoke out then it was overly warm. If it still looks intact then it is likely still good. Resistance is easily measured with a dmm's ohm-meter range. I'm curious what that resistor was used for? Resistors with wire terminal don't often have writing on them, just a colour code. Surface mount types sometimes have writing.
