- Global symbol assignment by
`def_sym()`

(#18) - Linear algebra: New
`do_la()`

function with convinience functions like`eigenval()`

,`eigenvec()`

,`QRdecomposition()`

; new vignette demonstrating these - Assumptions being made available, see e.g.
`symbol()`

and`ask()`

- Arbitrary precision arithmetic:
`N()`

function and vignette on “Arbitrary precision arithmetic” - Rename
`eigen_val()`

/`eigen_vec()`

to`eigenval()`

/`eigenvec()`

- More clear naming convention: R has expressions and caracas has symbols; in this connection
`as_r()`

was renamed to`as_expr()`

and`as_symbol()`

to`as_sym()`

. Also,`as_sym()`

changed argument from`declare_variables`

to`declare_symbols`

. - Changed internals such that
`der()`

,`der2()`

and`solve_sys()`

now takes multiple variables with`list()`

(or as a vector symbol) instead of`c()`

; see also`matrify()`

and`listify()`

- Added
`diag_()`

and`matrix_()`

(postfix`_`

to avoid name clashes) -
`sumf()`

renamed to`sum_()`

and`prodf()`

to`prod_()`

(postfix`_`

to avoid name clashes) -
`intf()`

renamed to`int()`

and`limf()`

to`lim()`

(because there are no name clashes with base R) - Call SymPy functions directy with
`sympy_func()`

- Added
`taylor()`

and`drop_remainder()`

- Minor bugs fixed
