Krippendorff has a paper (free and official versions) describing an adaptation of his measure of reliability α to continuous data, such as text. Specifically, it calculates the reliability of both unitizing (i.e., how the text is split into coded and uncoded units) and coding (i.e., which codes are assigned to what units).
I'm wondering if this has been implemented, say, in R. In his paper, Krippendorff mentions that a "computer program for calculating these [adaptations of α] is currently being developed." However, I could find no mention of or link to such software, neither on Krippendorff's site nor elsewhere. The paper is detailed enough that it would allow me to implement it myself, but if it's already been done no sense in reinventing the wheel.
Thanks in advance.
