Reduce number of warnings returned to console by Shiny

[innesbre]

Functions dependent on unfinished calculations are returning errors that Shiny returns as warnings to the console until the calculations they depend on are completed. These warnings aren't indicative of errors, just mistimed function evaluations, but they are spamming the console and if there are important warnings/errors, they're being buried in the noise.

I'm not sure if this is part of the same problem but when I run Shiny, the tSNE clusters are not shown on the screen. I have to manually select PCA then reselect tSNE to get the clusters to display.

Hi Paul, Issue #39 refers to that problem. It just cropped up recently, and I'm in the midst of tracking down the cause. In the meantime, toggling inputs as you describe is the work-around. Sorry for the inconvenience!
