Default and current tex options
Description
Options for functions in the texPreview package. When running R code, the object tex_opts
(default options) is not modified by chunk headers (local chunk options are
merged with default options), whereas tex_opts_current (current options)
changes with different chunk headers and it always reflects the options for
the current chunk.
Usage
tex_opts
tex_opts_current
Format
An object of class list of length 5.
An object of class list of length 5.
Details
Normally we set up the global options once in the first code chunk in a
document using tex_opts$set(), so that all latter chunks will
use these options. Note the global options set in one chunk will not affect
the options in this chunk itself, and that is why we often need to set global
options in a separate chunk.
Below is a list of default chunk options, retrieved via
tex_opts$get():
These options correspond to fields in the direct call to tex_preview, which are listed in explained
in the help manual.
Note
tex_opts_current is read-only in the sense that it does nothing if
you call tex_opts_current$set(); you can only query the options via
tex_opts_current$get().
Examples
tex_opts$get()
