  meta = NULL,
  doc_col = "doc_id",
  token_col = "token",
  space_col = NULL,
  doc_nav = NULL,
  token_nav = NULL,
  filename = NULL,
  css_str = NULL,
  header = "",
  subheader = "",
  n = TRUE,
  navfilter = TRUE,

)

`tokens`	A data.frame with a column for document ids (doc_col) and a column for tokens (token_col)
`meta`	A data.frame with a column for document_ids (doc_col). All other columns are added to the browser as document meta
`doc_col`	The name of the document id column
`token_col`	The name of the token column
`space_col`	Optionally, a column with space indications (" ", "\n", etc.) per token (which is how some NLP parsers indicate spaces)
`doc_nav`	The name of a column (factor or character) in meta, used to create a navigation bar for selecting document groups.
`token_nav`	Alternative to doc_nav, a column in the tokens. Navigation filters will then be used to select documents in which the value occurs at least once.
`filename`	Name of the output file. Default is temp file
`css_str`	A character string, to be directly added to the css style header
`header`	Optionally, specify the header
`subheader`	Optionally, specify a subheader
`n`	If TRUE, report N in header
`navfilter`	If TRUE (default) enable filtering with nav(igation) bar.
`top_nav`	A number. If token_nav is used, navigation filters will only apply to the top x values with highest token occurence in a document
`thres_nav`	Like top_nav, but specifying a threshold for the minimum number of tokens.
`colors`	Optionally, a vector with color names for the navigation bar. Length has to be identical to unique non-NA items in the navigation.
`style_col1`	Color of the browser header
`style_col2`	Color of the browser background

The name of the file where the browser is saved. Can be opened conveniently from within R using browseUrl()

url = create_browser(sotu_data$tokens, sotu_data$meta, token_col = 'token', header = 'Speeches')


view_browser(url)   ## view browser in the Viewer

if (interactive()) {
