Primefaces slider doesn't appear

I'm trying to add a primefaces slider element, but it doesn't appear/show/display at all. Like, I put it in <h:body> (<h:head> also exists), inside the <h:form> :

<h:inputHidden id="R"/> <p:slider for="R" minValue="2" maxValue="5" step="1" id="Rslider"/>

and have nothing in html in the place I put it (simply no tags).

Console logs this:

jquery-3.3.1.min.js:2 jQuery.Deferred exception: this.jq.slider is not a function TypeError: this.jq.slider is not a function
