Randomly Select Samples for Various Probability-Based Methods R package SampleSelectR version 1.0.0 Randomly select samples using simple random sampling (SRS), systematic sampling, and various probability proportional to size (PPS) methods, including systematic PPS and sequential PPS (i.e., Chromy's method). Also includes functionality to allocate sample sizes across strata using proportional, power, Neyman, and optimal allocation methods, and to select samples within strata. Designed to make survey sample design and selection reproducible, efficient, and transparent for survey statisticians and researchers. Sampling methods follow Kalton (1983) <doi:10.4135/9781412984683> and Chromy (1979) <http://www.asasrms.org/Proceedings/papers/1979_081.pdf>.
