Depends on the value. For values above a few hundred ohms, capacitive effects are more prevalent. Even the old ARRL handbooks tell you that. In either case, at any particular frequency, you can tune it out - if it matters, which frequently, it doesn't. When this thread started, it was about 220K ohm resistors for shunting electrolytics, where of course, reactance doesn't matter. For small signal stuff these days, chip resistors tend to be predominately capacitive.
