RDS-package This package provides functionality for carrying out estimation with data collected using Respondent-Driven Sampling. This includes Heckathorn's RDS-I and RDS-II estimators as well as Gile's Sequential Sampler estimator.
as.char converts to character with minimal loss of precision for numeric variables
as.rds.data.frame Coerces a data.frame object into an rds.data.frame object.
assert.valid.rds.data.frame Does various checks and throws errors if x is not a valid rds.data.frame
bottleneck.plot Bottleneck Plot
compute.weights Compute estimates of the sampling weights of the respondent's observations based on various estimators
convergence.plot Convergence Plots
count.transitions Counts the number or recruiter->recruitee transitions between different levels of the grouping variable.
cumulative.estimate Calculates estimates at each successive wave of the sampling process
