Description
meval is a wrapper for eval, to
allow use in sapply.
Usage
1
meval(equation_txt)
Arguments
equation_txt
The text of the equation to run
eval on – e.g., from a cell of a
text-based transition matrix.
Details
This is an attempt to speed up the use of
eval; in general use of eval
to convert a text version of a transition matrix to a
numeric version with probabilities is a poor, slow
choice; but it can be useful for examples and display
purposes.
See cladoRcpp for fast C++
implementations of transition matrix setup.
Value
outval The numeric result of eval.
Note
Go BEARS!
