title: fmsb - Radar chart function. Missing polygons in some of the radar plots, in grid
body: <p>I'm having a weird issue with the radar chart function from the fmsb R package. I'm trying to create a grid with a separate plot for each row using the following code.</p>
  <pre><code>avgsol &lt;- avg %&gt;% select(-group)
  avgsol &lt;- rbind(rep(100,17) , rep(0,17) , avgsol)
  # Prepare color
  
  colors_border=colormap(colormap=colormaps$viridis, nshades=6, alpha=1)
  colors_in=colormap(colormap=colormaps$viridis, nshades=6, alpha=0.3)
  
  # Prepare title
  mytitle &lt;- c(&quot;Baseline&quot;, &quot;3Hz&quot;, &quot;7Hz&quot;, &quot;8Hz&quot;, &quot;10Hz&quot;, &quot;13Hz&quot;, &quot;15Hz&quot;,&quot;19Hz&quot;)
  
  # Split the screen in 6 parts
  par(mar=rep(0.8,4))
  par(mfrow=c(2,4))
  
  # Loop for each plot
  for(i in 1:8){
    
    # Custom the radarChart !
    radarchart( avgsol[c(1,2,i+2),], axistype=0, 
                
                #custom polygon
                pcol=colors_border[i] , pfcol=colors_in[i] , plwd=4, plty=1 , 
                
                #custom the grid
                cglcol=&quot;grey&quot;, cglty=1, axislabcol=&quot;grey&quot;, caxislabels=seq(0,20,5), cglwd=0.8,
                
                #custom labels
                vlcex=0.8,
                
                #title
                title=mytitle[i]
    )
  }
  
  </code></pre>
  <p>avg just contains a row of 8 rows of numeric data over 16 columns. Not sure why most of the plot of works but the last part breaks.</p>
