<br>
Are you going to add support for calling the RRDTool standard library functions, to create graphs or update the data?<br>

<div class="gmail_default" style="font-size:x-small">Hello,<br>
<br>
I spent the past few months implementing an R package that makes it possible to directly import and work with
<span tabindex="-1" id=":1m0.1" class="" style="">RRD</span> files in R.<br>
<br>
There are currently three ways to use the package:<br>
<br>
- <span tabindex="-1" id=":1m0.2" class="" style="">importRRD</span>("<span tabindex="-1" id=":1m0.3" class="" style="">filename</span>", "cf", start, stop, step) - returns a data.frame containing the desired portion of an
<span tabindex="-1" id=":1m0.4" class="" style="">RRA</span><br>
- <span tabindex="-1" id=":1m0.5" class="" style="">importRRD</span>('filename") - imports everything in the
<span tabindex="-1" id=":1m0.6" class="" style="">RRD</span> file into a list of data.frame objects (one per
<span tabindex="-1" id=":1m0.7" class="" style="">RRA</span>)<br>
<br>
(the <span tabindex="-1" id=":1m0.8" class="" style="">metadata</span> is read and appropriate names are given to columns and list elements)<br>
<br>
- <span tabindex="-1" id=":1m0.9" class="" style="">getVal</span>("<span tabindex="-1" id=":1m0.10" class="" style="">filename</span>", "cf", step, timestamp) - optimized for getting the values at a specific timestamp, uses a cache to minimize the read frequency<br>
<br>
Please, feel free to install and test the package: https://<span tabindex="-1" id=":1m0.11" class="" style="">github</span>.com/<span tabindex="-1" id=":1m0.12" class="" style="">pldimitrov</span>/<span tabindex="-1" id=":1m0.13" class="" style="">Rrd</span><br>
<br>
I'm now getting close to finishing it so any feedback is more than welcome!<br>
<br>
Thanks,<br>
