Hiding the R code in Rmarkdown knit and just showing the results

Question

In my R Markdown documents  I sometimes want to just generate a report without showing the actual code  specially when I send it to my boss   How can I hide the R code and just show the graph and results   For example   --- output  html document ---      r fig width 16  fig height 6  plot cars        This shows both the commands and the plot  How can I remove the commands from my HTML report

Sure  just do      r someVar  echo FALSE  someVariable       to show some  previously computed  variable someVariable   Or run code that prints etc pp    So for plotting  I have eg      Impact of choice of          r somePlot  echo FALSE  plotResults Res  Grid   some text    some more text         where the plotting function plotResults is from a local package

Alternatively  you can also parse a standard markdown document  without code blocks per se  on the fly by the markdownreports package

Just aggregating the answers and expanding on the basics  Here are three options   1  Hide Code  individual chunk   We can include echo FALSE in the chunk header       r echo FALSE  plot cars        2  Hide Chunks  globally    We can change the default behaviour of knitr using the knitr  opts chunk set function  We call this at the start of the document and include include FALSE in the chunk header to suppress any output   --- output  html document ---      r include   FALSE  knitr  opts chunk set echo FALSE           r  plot cars        3  Collapsed Code Chunks  For HTML outputs  we can use code folding to hide the code in the output file  It will still include the code but can only be seen once a user clicks on this  You can read about this further here   --- output    html document      code folding   hide  ---       r  plot cars

Might also be interesting for you to know that you can use    r echo FALSE  results  hide  message FALSE  a lt -as numeric rnorm 100   hist a  breaks 24    to exclude all the commands you give  all the results it spits out and all message info being spit out by R  eg  after library ggplot  or something
