stocnet/migraph: Release v1.6.10

Package

• Raised the minimum versions of the stocnet dependencies: manynet 2.3.1 and autograph 1.2.2
• Updated CONTRIBUTING
• Fixed the attach-time version check by parsing version strings with package_version()

Models

• Fixed play_diffusions() for stocnet input via initial coercion (re stocnet/manynet#172)

Data

• Converted every mpn_* dataset to the stocnet class, in line with {manynet}
• Removed the weight tie attribute from the datasets that are not weighted
• Merged mpn_cow
  • This combines interstate trade and IGO membership into one multilevel network of 116 "states" and 40 "IGOs", with trade and membership tie layers
  • mpn_cow_trade and mpn_cow_igo are retained, because {manynet} currently reads a network with two named modes as undirected, which symmetrises the trade layer of mpn_cow, and because to_layer() does not recover that layer either (stocnet/manynet#170, stocnet/manynet#171)
  • Fixed mpn_cow_trade missing-data coding from -9 (759 cells) to NA
  • Added a scope node attribute to the IGOs in mpn_cow and mpn_cow_igo, recording whether an organisation is "global" or "regional"
• Merged mpn_senate
  • This combines the 112th Congress data into one multilevel network of 93 senators, 78 PACs, and 25 bills
  • mpn_senate_dem and mpn_senate_rep are not party networks but record two communities of one network and their intersection; the community node attribute holds "A", "B", or "both"
  • Cells that neither community covers were never observed, and are recorded as missing rather than as absent ties
  • Where the two communities disagree, in 9 of their 640 shared cells, community A governs, since it agrees with the overlap file in all 640
  • mpn_senate_dem, mpn_senate_rep, and mpn_senate_over are deprecated and will be removed in 1.8.0
• Merged mpn_evs_ita, mpn_evs_deu, and mpn_evs_gbr
  • These combine each country's European Values Study data for 1990 and 2008 into one two-mode network, with the year recorded in the time tie attribute
  • These are repeated cross-sections, not a panel, so use over_time() not over_waves()
  • The six year-by-country datasets are deprecated and will be removed in 1.8.0
• Converted mpn_elite_mex
• Converted mpn_elite_usa_advice
  • It now names its two modes, "directors" and "think tanks"
• Converted mpn_elite_usa_money
  • It now names its three modes, "elites", "organisations", and "candidates"
• Converted mpn_bristol
  • It now names its three modes, "individuals", "organisations", and "events"
• Converted mpn_ryanair
