v1.7.2

[jhollway]

Package

• Fixed the attach-time version check so that it no longer leaves stale messages for up to a week

Models

• Fixed play_diffusions() so that it drops, with a warning, runs where nothing spreads beyond the seed,
  instead of stopping with "arguments imply differing number of rows"
• Set a seed in the test_fit() test so that it does not fail at random

Tutorials

• Updated intro tutorial
  • Added sections on types, missing data, indexing with [, [[, and $,
    changing data frames with mutate() and filter(), random numbers and seeds,
    reading errors and writing reproducible examples, and files and projects
  • Moved packages to a closing "Where next" section that points to the {manynet} tutorials
  • Replaced dead links, removed T/F shorthand, and fixed typos

inst/tutorials/tutorial0/tutorial0.Rmd:356

• $ is not defined for atomic vectors such as ages; trying ages$Ben errors. Please reserve $ for lists and data frames here and describe [[ as the named-vector accessor so beginners are not taught an invalid operation.

The `$` and `[[` operators extract a single named element:

inst/tutorials/tutorial0/tutorial0.Rmd:849

• question() and answer() in this tutorial come from {learnr}, so saying everything except {dplyr} is base R is inaccurate. Qualify this statement to distinguish the tutorial infrastructure and the {dplyr} examples from the base-R code.

Everything in this tutorial (apart from `{dplyr}`) is part of "base" R.
