Stryd Leg Spring Stiffness

[Chris O'Shannassy]

Hi;

Just wondering if anybody knows how to see the Leg Spring Stiffness data (and also Form Power) output in the latest Stryd FIT files?  I think the data may be getting read in as "xData" (since they're not standard recognised channels) but I can't see any way to work with xData.  (I'm using the 3.4 RC2 version of GC.)

XDATA is available in formula expressions, you can use expressions in custom metrics, trend chart formulas and ride plot user data.

see: https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Formula-Syntax-and-Expressions

You can use it in R

see: https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Working-with-R

Once we're ready to release I'll get a tutorial sorted to explain how this works in 3.4

There is still room for improvement in 4.0, but we needed to get the release done as FIT 2.0 is already out there

Thanks Mark - just installed R on my computer (Mac/Sierra 10.12.1) and was going to have a play with it in GC (I've used R a little previously, but a long time ago.) however I can't find any installation instructions in the wiki?  I watched your video on Vimeo, but I'm stuck at an earlier stage.  I've set the R installation directory to "/Library/Frameworks/R.framework/Resources" which is what R.home() reports, and also to "/Applications/R.app/Contents/MacOS" which is where the binary is, but both of those just leave me with a blank "R Chart".  (As in the screenshot.)

Any pointers as to where I've gone wrong?

Also, you can get an example R chart from the cloudDB to play with ?

Download chart is an option on the chart bar menu.
