Shiny Dull: Plots are blurrier in Shiny than in R-Studio

[Robert Sloan]

Is there a way to make the plots in Shiny as clear and crisp as they are in R-Studio?

It seems like the dots per inch doesn't match the display i.e. fonts and lines seem scaled and thus blurred.

I'm not sure how you're outputting plots so I can only suggest messing with Cairo options.

library(Cairo); options(shiny.usecairo=TRUE); 

or

options(shiny.usecairo=FALSE)

I know many people have had this kind of issue and there are a few of these questions on stackoverflow. 

for me, my png() output looked worse when hosted on an rstudio server for some reason so I had to set shiny to not use cairo to get antialiased plots again.

Not sure if that'll work for you though. It
