scientific notation for \Sexpr{}

[yihui]

may want this in the inline hook: http://stackoverflow.com/q/8366324

Can someone provide an example of how to disable this scientific formatting for \Sexpr{}?

[ramnathv]

you can do this by redefining the inline hook in your document by adding the following chunk

<<disable-sci-format, echo = F>>=
knit_hooks$set(inline = function(x) identity(x))

Yes that is one way to do it. Another (more natural) way is to set the option scipen; see ?options

Basically larger scipen (default 0) will bias towards fixed notation, e.g. options(scipen = 8) (use fixed notation unless it is greater than 10^{8+4} or less than 10^{-12})

Thanks, that worked.
