Title: Design and Monitoring of Survival Trials Accounting for Complex
Description: Calculates various functions needed for design and monotoring survival trials
accounting for complex situations such as delayed treatment effect, treatment crossover, non-uniform accrual,
and different censoring distributions between groups. The event time distribution is assumed to be
piecewise exponential (PWE) distribution and the entry time is assumed to be piecewise uniform distribution.

As compared with Version 1.1.0, this version includes the calculation of the restricted mean survival time and weighted log-rank statistics.

As compared with Version 1.2.1, two more types of hybrid crossover are added.
A bug is corrected in the function "pwecx" that calculates the crossover-adjusted survival, distribution,
density, hazard and cumulative hazard functions.
Also, to generate the crossover-adjusted event time random variable,  a more efficient
algorithm is used and the output includes crossover indicators.

Description: Utilities for working with air quality monitoring data
with a focus on small particulates (PM2.5) generated by wildfire
smoke. Functions are provided for downloading available data from
the United States Environmental Protection Agency (US EPA) and
it's AirNow air quality site. Additional sources of PM2.5 data
made accessible by the package include: AIRSIS (password protected),
the Western Regional Climate Center (WRCC) and the open source site OpenAQ.
