Interactive Reingold-Tilford tree diagrams created using 'D3.js', where every node can be expanded and collapsed by clicking on it.
    Tooltips and color gradients can be mapped to nodes using a numeric column in the source data frame.
    See 'collapsibleTree' website for more information and examples.

Map functions while capturing results, errors, warnings, messages and other output tidily, then filter and summarise data frames or lists on the basis of those side effects.

Provides the basic functionality to interact with the Collatz conjecture.
    The parameterisation uses the same (P,a,b) notation as Conway's generalisations.
    Besides the function and reverse function, there is also functionality to retrieve
    the hailstone sequence, the "stopping time"/"total stopping time", or tree-graph. 
    The only restriction placed on parameters is that both P and a can't be 0.

Provides high performance container data types such
    as queues, stacks, deques, dicts and ordered dicts. Benchmarks
    <https://randy3k.github.io/collections/articles/benchmark.html> have
    shown that these containers are asymptotically more efficient than
    those offered by other packages.

Check for namespace collisions between a string input (your function or package name) 
    and half a million packages and functions on CRAN.

Tool to assessing whether the results of a study could be influenced by
    collinearity. Simulations under a given hypothesized truth regarding effects of an
    exposure on the outcome are used and the resulting curves of lagged effects are
    visualized. A user's manual is provided, which includes detailed examples (e.g. a
    cohort study looking for windows of vulnerability to air pollution, a time series
    study examining the linear association of air pollution with hospital admissions,
    and a time series study examining the non-linear association between temperature and
    mortality). The methods are described in Basagana and Barrera-Gomez (2021) <doi:10.1093/ije/dyab179>.
