html_matrix: HTML Representation

Description

Creates from a vector, a matrix, an array, or a table, an HTML representation of it. The HTML representation has one column and one row more than the data. The additional row and column are used in order to have a title (top left), the column names (top), and the row names (left).

You can set the style attributes (<td style="...">) via hm_cell, hm_title, hm_col, and hm_row. For example: hm_cell(hm, 1, 1, text_align="right") will lead to (<td style="text-align:right;">) for the cell (1,1), and any unnamed element will change the cell value. Note: since - is an operator in R, we use _ instead. Of course, someone could use "text-align"="right", but I am lazy.

Usage

html_matrix(x, ...)
# S3 method for default
html_matrix(
  x,
  ...,
  byrow = FALSE,
  numeric = list(text_align = "right"),
  integer = list(text_align = "right"),
  char = list(text_align = "left"),
  logical = list(text_align = "right"),
  border = "#999999"
)
html_mx(x, ...)

Value

Returns an html_matrix.
