Once upon a time, I changed my `ggplot2` font using `windowsFonts(Times=windowsFont(&quot;TT Times New Roman&quot;))`. Now, I can&#39;t get it off of this.

In trying to set `family=&quot;&quot;` in `ggplot2` `theme()`, I can&#39;t seem to generate a change in fonts as I compile the MWE below with different font families.

    library(ggplot2)
    library(extrafont)
    loadfonts(device = &quot;win&quot;)
    
    a &lt;- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
    		ggtitle(&quot;Fuel Efficiency of 32 Cars&quot;) +
    		xlab(&quot;Weight (x1000 lb)&quot;) + ylab(&quot;Miles per Gallon&quot;) +
    		theme(text=element_text(size=16, 
    #		family=&quot;Comic Sans MS&quot;))
    #		family=&quot;CM Roman&quot;))
    #		family=&quot;TT Times New Roman&quot;))
    #		family=&quot;Sans&quot;))
    		family=&quot;Serif&quot;))
    
    
    print(a)
    print(&quot;Graph should have refreshed&quot;)

R is returning a warning `font family not found in Windows font database`, but there was a tutorial I was following (if I can find it again I will update the link here) that said this was normal and not a problem.  Also, somehow this worked at one point because my graph once used some arial or helvitica type font.  I think this has always been a present warning even during the initial times migration.

UPDATE

when I run `windowsFonts()` my output is

&gt; $serif [1] &quot;TT Times New Roman&quot;
&gt; 
&gt; $sans [1] &quot;TT Arial&quot;
&gt; 
&gt; $mono [1] &quot;TT Courier New&quot;

But, this is after I ran `font_import()` so I can only conclude that my fonts are not being saved in the right place.  The code that ran the `font_import()` request actually loads the libraries with:

    LocalLibraryLocation &lt;- paste0(&quot;C:\\Users\\&quot;,Sys.getenv(&quot;USERNAME&quot;),&quot;\\Documents&quot;,&quot;\\R\\win-library\\3.2&quot;);
    	.libPaths(c(LocalLibraryLocation, .libPaths()))
