Wrapper of knitr::include_graphics
to Deal with URLs and Invalid File Types
Código: R/include_graphics2.R
include_graphics2.Rd
Deals with URL paths and invalid file types passed to path
of include_graphics
. When the output format
of the R Markdown is PDF
, and an URL is passed to
path
, the figure is automatically downloaded from the URL
and included using the local relative path.
If a figure has an invalid file extension for PDF output
(e.g. .gif
, .svg
), the function passed to
handler
is used to override the default behavior:
inserting figures with knitr::include_graphics
.
