Computation of t-year survival probabilities and t-year
    risks with right censored survival data. The Kaplan-Meier estimator
    is used to provide estimates for data without competing risks and
    the Aalen-Johansen estimator is used when there are competing risks.
    Confidence intervals and p-values are obtained using either usual
    Wald-type inference or empirical likelihood inference, as described
    in Thomas and Grunkemeier (1975) <doi:10.1080/01621459.1975.10480315>
    and Blanche (2020) <doi:10.1007/s10985-018-09458-6>. Functions for
    both one-sample and two-sample inference are provided. Unlike Wald-type
    inference, empirical likelihood inference always leads to consistent
    conclusions, in terms of statistical significance, when comparing
    two risks (or survival probabilities) via either a ratio or a difference.

Manage time-series data frames across time zones, resolutions, and date ranges, 
    while filling gaps using weekday/hour patterns or simple fill helpers or plotting them interactively.
    It is designed to work seamlessly with the tidyverse and dygraphs environments.

Produce an HTML page containing horizontal strips that symbolize events in a person's lsife. Since this is entirely a visualization, the image <https://barryzee.github.io/henry-timeline/henry.html> will show the basic use to show a timeline of events. The image <https://barryzee.github.io/vermeer/cssOverlay.html> shows how to correlate two timelines of events. A brief description is available at <https://barryzee.github.io/timeLineGraphics_manuscript/golden_age.html>.

Approaches for incorporating time into network analysis. Methods include: construction of time-ordered networks (temporal graphs); shortest-time and shortest-path-length analyses; resource spread calculations; data resampling and rarefaction for null model construction; reduction to time-aggregated networks with variable window sizes; application of common descriptive statistics to these networks; vector clock latencies; and plotting functionalities. The package supports <doi:10.1371/journal.pone.0020298>.
