R Packages worth a look

Spectral Transmittance Data for Filters (photobiologyFilters)
A data only package with spectral ‘transmittance’ data for frequently used filters and similar materials. Plastic sheets and films; optical glass and ordinary glass and some labware.

Knowledge Space Theory Input/Output (kstIO)
Knowledge space theory by Doignon and Falmagne (1999) <doi:10.1007/978-3-642-58625-5> is a set- and order-theoretical framework which proposes mathematical formalisms to operationalize knowledge structures in a particular domain. The ‘kstIO’ package provides basic functionalities to read and write KST data from/to files to be used together with the ‘kst’, ‘pks’ or ‘DAKS’ packages.

Simultaneous CIs for Ratios of Means of Log-Normal Populations with Zeros (LN0SCIs)
Construct the simultaneous confidence intervals for ratios of means of Log-normal populations with zeros. It also has a Python module that do the same thing, and can be applied to multiple comparisons of parameters of any k mixture distributions. And we provide four methods, the method based on generalized pivotal quantity with order statistics and the quantity based on Wilson by Li et al. (2009) <doi:10.1016/j.spl.2009.03.004> (GPQW), and the methods based on generalized pivotal quantity with order statistics and the quantity based on Hannig (2009) <doi:10.1093/biomet/asp050> (GPQH). The other two methods are based on two-step MOVER intervals by Amany H, Abdel K (2015) <doi:10.1080/03610918.2013.767911>. We deduce Fiducial generalized pivotal two-step MOVER intervals based on Wilson quantity (FMW) and based on Hannig’s quantity (FMWH). All these approach you can find in the paper of us which it has been submitted.
