Details

Function char_to_matrix() gives very basic conversion between character vectors and free objects. Current functionality is limited to strings like “aaabaacd”, which would give \(a^3ba^2cd\). It would be nice to take a string like “a^3b^(-3)” but this is not yet implemented.

Function char_to_free() is a vectorized version that coerces output to free.

rfree(10,3) + as.free('xxxxxxxxxxxx')

as.free(letters)*7

all(is.id(as.free(letters) + as.free(LETTERS)))


as.free('')  # identity element
