Description

Convert between .R, .Rmd, .mm according to the given file names, and create a markmap widget

Usage

mm(from = NULL, to = NULL, type = c("file", "text", "dir"), root = NA, 
    show_files = TRUE, remove_curly_bracket = TRUE, bookdown_style = TRUE, 
    widget_name = NA, width = NULL, height = NULL, elementId = NULL, 
    options = markmapOption(preset = "colorful"), method = c("regexpr", 
        "pandoc"))

Arguments

from

character. The path of the input file, or the input markdown text, or the path to the directory. Dependent on 'type'.

to

character. The path of the output file.

type

character. The type of the input. If type == 'dir' and the OS is LinUx, the 'tree' command must be pre-installed: sudo apt-get install tree.

root

character. a string displayed as the root of the mind map

show_files

logical. Whether to show files in a directory. Only valid when type == 'dir'.

remove_curly_bracket

logical. Whether to remove #ID in the headers of the markdown file (usually in a 'bookdown' https://github.com/rstudio/bookdown project).

bookdown_style

logical. whether the markdown files are in bookdown style, i.e. index.Rmd at the beginning, # (PART), # (APPENDIX) and # References as an upper level of normal # title

widget_name

The file name of the html widget to save.

width

the width of the markmap

height

the height of the markmap

elementId

character.

options

the markmap options

method

"regexpr" uses regular expressions, 'pandoc' uses pandoc to find the headings.

Value

A HTML widget object rendered from a given document.

Details

For LinUx OS and mac OS, the 'tree' command must be pre-installed before using 'show_files = FALSE'.

• Linux: sudo apt-get install tree

• mac: install Homebrew first. Then in the terminal: brew install tree.
