r - RMarkdown: preserve source code formatting in code cell -


my rmarkdown source looks (screenshot rstudio):

rstudio screenshot (notice empty lines)

when press ctrl+shift+k got view expected (with empty lines). however, if run chunk (evaluate) , compile (ctrl+shift+k), get:

compilse (no empty lines)

is there way how preserve empty lines in source code? (i checked knitr options: strip.white=false, tidy=true, tidy.opts=list(blank=true) no joy.)

i'm using rstudio 1.0.153

as far can see, can't html notebook. if don't need special notebook features, can ask html_document instead of html_notebook , formatting preserved. if need notebook features, need make feature request on rmarkdown development page https://github.com/rstudio/rmarkdown add this.
