Help Changing the Throttle Cable on a C10

When observing the bike from the RH side, rotate the center cable mechanism CW so the carbs are at full throttle. This will bring the “pull” cable access “notch” so it faces the rear of the bike, and more accessible from the top. During the time you are rotating the mechanism, pay attention to the individual carb linkages and you will see a gap form between a stop and a section of the linkage. When the carbs are at full throttle, find a suitable flat blade screw driver and wedge it in this gap to hold the carbs open once you’ve released the cable mechanism. This will give you ample time to fiddle with getting the cable end in the hole and engaged. A pair of long, long-nosed needle nose pliers, or a long hemostat works best in getting the cable end in place.

Nice example of converting wide to tall data with tidyr

Nice example.

R Markdown

R Markdown is an authoring format that enables easy creation of dynamic documents, presentations, and reports from R. It combines the core syntax of markdown (an easy-to-write plain text format) with embedded R code chunks that are run so their output can be included in the final document. R Markdown documents are fully reproducible (they can be automatically regenerated whenever underlying R code or data changes).
