+Render a data set to an I/O stream in MIME type `mime`.
 
 # Arguments
 - `io::IO`: The I/O stream to which `ds` will be printed.
 - `mime::MIME`: supported MIME types are: `"text/plain"`, `"text/html"`, `"text/latex"`,
   `"text/csv"`, `"text/tab-separated-values"` (the last two MIME types do not support
    showing `#undef` values)
-- `ds::AbstractDataset`: The data frame to print.
+- `ds::AbstractDataset`: The data set to print.
 
 Additionally selected MIME types support passing the following keyword arguments:
 - MIME type `"text/plain"` accepts all listed keyword arguments and therir behavior
   is identical as for `show(::IO, ::AbstractDataset)`
 - MIME type `"text/html"` accepts `summary` keyword argument which
-  allows to choose whether to print a brief string summary of the data frame.
