- Fixes swapped wedge and vee symbols (#55, credit to @ebolove)

- Round brakets after exponent render correctly (fixes #49)
`\cap`

now renders correctly (fixes #52)- Escaped and non-escaped square brackets now render correctly, including with exponents (fixes #48)

- Fixes bug where certain commands would fail outside of math mode
(e.g.
`TeX(r"(\alpha + \beta)")`

) (fixes #45). - Fixes edge case where
`TeX(r"($^{18}$ O)")`

(e.g. a free-standing superscript or subscript) would not render.

- Fix an edge case encountered with back-to-back spacing or certain
types of commands (e.g.
`TeX(r"(a \,\, b)"`

)) (fixes issue #40) - Fix handling of compare operators
(
`=, <, >, \ge, \le`

) (fixes issue #38) `TeX("")`

returns`expression('')`

(an empty expression of length 1) (fixes issue #40)

- Completely rewritten parser that is much more robust, produces valid plotmath expressions in more situations, and improved rendering by making use of more plotmath features.
- Added a vignette containing a browsable gallery of LaTeX commands
supported. You can pull it up using
`vignette("supported-commands", package = "latex2exp")`

. - Added the following LaTeX commands and symbols:
`\Upsilon`

and`\varpi`

for Greek letter variants`\uparrow`

,`\downarrow`

,`\Uparrow`

,`\Downarrow`

,`\to`

`\euro`

for the euro character`\langle`

,`\rangle`

for angle bracket (supported in R 4.1)`\lceil`

,`\rceil`

,`\lfloor`

,`\rfloor`

for ceil/floor brackets`\|`

for double-pipe brackets (`\norm{expr}`

is an alternative command for typesetting a vector norm).- Note that the angle, ceil, floor, pipe and double pipe brackets are
*not*scalable delimiters, because of plotmath limitations. `\bra`

,`\ket`

,`\braket`

for representing vectors with the braket notation`\smiley`

,`\diamond`

,`\sharp`

,`\eightnote`

,`\twonotes`

,`\sun`

,`\venus`

,`\mars`

,`\Exclam`

,`\dagger`

,`\ddagger`

,`\(up|down|right|left)triangle`

- Improved the appearance of round parentheses.
`TeX(r"($\alpha(\beta)$)")`

now renders more similarly to how plotmath renders the expression`alpha(beta)`

. - Improved the appearance of
`,`

,`'`

and`''`

in math mode. - Improved the appearance of
`\frac`

fractions. Now a small space is inserted after the fraction, so that multiple fractions are separated. - Added a test suite covering a large number of LaTeX expressions, edge cases, and examples from GitHub.
- Refactored and improved code documentation.

- Fixes #33 (adds
`\lceil, \rceil, \lfloor, \rfloor`

) - Fixes #24 (can mix & match different types of brackets,
e.g.
`TeX("$\\left(\\frac{M}{L}\\right.$")`

)

- Update documentation to use the new raw strings introduced in R 4.0
(which lets one do away with the quoting of the backslash character;
e.g. one can use
`TeX(r'($\alpha^\beta$)')`

rather than`TeX('\\alpha^\\beta)`

) - Adds parameters
`bold`

and`italic`

to`TeX()`

. These can be used to make the entire expression bold or italic. - Adds
`\phantom{}`

(PR)

- Deprecated the
`latex2exp()`

function; use`TeX()`

instead. - Added
`\lbrack`

and`\rbrack`

to type left and right square brackets.

Fixes bug #4 (“fix parsing of numbers”), where certain numbers inside formulas where not parsed correctly.

Fixes bug #3 (“subscript and superscript style”).
`latex2exp`

now renders combined subscripts and superscripts
correctly.

Fixes bug #2 (white space causes unexpected behaviour).
`latex2exp`

should now be a bit more compliant with how LaTeX
handles whitespace.

`latex2exp`

is now a proper package.

Formulas must now be enclosed between dollar characters ($), as in LaTeX proper. Text does not need to be enclosed in \text tags anymore.
