graphTweets 0.5.1

Better use of tidyeval to improve usage of the package in functions.

graphTweets 0.5.0

• gt_co_edges replaces gt_edges_hashes, it now works with other columns than just hashtags.
• gt_edges_hash is deprecated in favour of gt_edges.
• gt_edges_bind and gt_co_edges_bind added to bind edges together and build more complex graphs.
• Escape hatches, functions ending in _ are no longer necessary and are thus deprecated.

The origin gt_edges functions, first part of the package in 2014, was extracting @tagged users from tweets' text with convoluted regular expressions: it is no longer necessary as rtweet now returns mentions_screen_name, hence the aforementioned changes.

graphTweets 0.4.3

• Added gt_edges_hashes_ and gt_edges_hashes to build networks of #hashtags co-mentions.
• Added %<-% from the zeallot package to unpack the nodes and edges.
• Fixed gt_dyn bug where lifetime was not working properly.

graphTweets 0.4.2

Removed splitstackshape dependency ahead of its archival; now uses tidyr.

graphTweets 0.4.1

• gt_nodes returns number of n_edges, the number of edges the node is present in.
• gt_edges_hash and respective escape hatch added
• gt_dyn returns correct start and end.

graphTweets 0.4.0

Major release: overhaul to 1) make computations much faster, 2) make the whole package more tidyverse friendly and 3) switch to rtweet as main source.

• getEdges & getNodes are now deprecated in favour of gt_edges and gt_nodes
• dynamise deprecated in favour of gt_dyn
• magrittr pipe added.
• gt_collect added: use to get to collect edges and nodes as list.
• gt_graph added: use to convert to igraph object.
