show str(...) as table in R Markdown

Viewed 3698

Is there a library or function for r-markdown to show the structure of a dataframe as a table? Something similar tot the output of str(myDataFrame) but as a pretty formatted r-markdown table?

For example the following output should be shown as at least the colums holding the feature names, and the datatypes. Some example values would be nice but are not required.

str(mtcars)
'data.frame':   32 obs. of  11 variables:
 $ mpg : num  21 21 22.8 21.4 18.7 18.1 14.3 24.4 22.8 19.2 ...
 $ cyl : num  6 6 4 6 8 6 8 4 4 6 ...
