let you export continuous glucose monitoring values. Here I describe how
you can use these data to generate a picture of you glucose percentiles
with the <a href="https://irinagain.github.io/iglu/">R package Iglu</a>.</p>
<p style="line-height: 108%; margin-bottom: 0.11in">First you have to save
your streaming data. In Juggluco for Android you can select Export from
the left middle menu and press Stream to save it in some file. You need to
save in mg/dL so before you save it you should set mg/dL in Settings. The
resulting graph is also in mg/dL. This file you can then transfer to you
computer.</p>
<p style="line-height: 108%; margin-bottom: 0.11in">You can also run cmdline
juggluco on you computer. Setting it to receive glucose values via IP/TCP
connection by selecting Mirror in the left middle menu and adding a
connection with you computers' IP and Stream checked. On you computer you
press </p>
<pre style=" line-height: 108%; margin-bottom: 0.11in">juggluco -ra</pre>
Set unit to mg/dL:
<pre style=" line-height: 108%; margin-bottom: 0.11in">juggluco -G</pre>
Make it a receiver and run in the background by pressing:
<pre style=" line-height: 108%; margin-bottom: 0.11in">juggluco&amp;</pre>
<p style="line-height: 108%; margin-bottom: 0.11in">If the data are
transferred to the computer, you can press </p>
<pre style=" line-height: 108%; margin-bottom: 0.11in">juggluco -B filename </pre>
<p style="line-height: 108%; margin-bottom: 0.11in">to save the stream data
to filename. See <a href="https://www.juggluco.nl/Juggluco/cmdline/index.html">https://www.juggluco.nl/Juggluco/cmdline/index.html</a>
for more information about cmdline juggluco.</p>
