</p>
<p>Inspired by your comment, "<span style="font-family:Calibri,Arial,Helvetica,sans-serif,'Apple Color Emoji','Segoe UI Emoji',NotoColorEmoji,'Segoe UI Symbol','Android Emoji',EmojiSymbols;font-size:16px">Perhaps an issue with a missing value not

<p>However, I am getting the warning messages still.</p><span class="">

<div>It might help us diagnose the problem if you printed out summaries of the lat, lon, and data variables. </div>
