flextable R package

The flextable package provides a framework for easily create tables for reporting and publications. Tables can be easily formatted with a set of verbs such as bold(), color(), they can receive a header of more than one line, cells can be merged or contain an image. The package make it possible to build any table for publication from a data.frame.

set_flextable_defaults(
  font.family = "Arial", font.size = 10, 
  border.color = "gray")

flextable(head(cars)) %>% 
  bold(part = "header") %>% 
  add_footer_lines("The 'cars' dataset")

Tables can be embedded within HTML, PDF, Word and PowerPoint documents from R Markdown documents and within RTF or Microsoft Word or PowerPoint documents with package officer. Tables can also be rendered as R plots or graphic files (png).

flextable(mtcars) %>% 
  theme_vanilla() %>% 
  save_as_docx(path = "mytable.docx")

A flextable object is a data.frame representation. An API is available to let R users create tables for reporting and control their formatting properties and their layout. The package provides functions that give control over:

header, body and footer content
text, paragraphs, cells and border formatting of any element
displayed values

The package also offers a set of high-level functions that allow tabular reporting of statistical models and the creation of complex cross tabulations.
