network_g2g {vivainsights}

Create a network plot with the group-to-group query

Description

Pass a data frame containing a group-to-group query and return a network plot. Automatically handles "Within Group" and "Other_collaborators" values within query data.

Usage

network_g2g(
  data,
  primary = NULL,
  secondary = NULL,
  metric = "Group_collaboration_time_invested",
  algorithm = "fr",
  node_colour = "lightblue",
  exc_threshold = 0.1,
  org_count = NULL,
  subtitle = "Collaboration Across Organizations",
  return = "plot"
)

Arguments

data

Data frame containing a group-to-group query.

primary

String containing the variable name for the Primary Collaborator column.

secondary

String containing the variable name for the Secondary Collaborator column.

metric

String containing the variable name for metric. Defaults to Group_collaboration_time_invested.

algorithm

String to specify the node placement algorithm to be used. Defaults to "fr" for the force-directed algorithm of Fruchterman and Reingold. See https://rdrr.io/cran/ggraph/man/layout_tbl_graph_igraph.html for a full list of options.

node_colour

String or named vector to specify the colour to be used for displaying nodes. Defaults to "lightblue".

• If "vary" is supplied, a different colour is shown for each node at random.

• If a named vector is supplied, the names must match the values of the variable provided for the primary and secondary columns. See example section for details.

exc_threshold

Numeric value between 0 and 1 specifying the exclusion threshold to apply. Defaults to 0.1, which means that the plot will only display collaboration above 10% of a node's total collaboration. This argument has no impact on "data" or "table" return.

org_count

Optional data frame to provide the size of each organization in the secondary attribute. The data frame should contain only two columns:

• Name of the secondary attribute excluding any prefixes, e.g. "Organization". Must be of character or factor type.

• "n". Must be of numeric type. Defaults to NULL, where node sizes will be fixed.

subtitle

String to override default plot subtitle.

return

String specifying what to return. This must be one of the following strings:

• "plot"

• "table"

• "network"

• "data"

See Value for more information.

Value

A different output is returned depending on the value passed to the return argument:

• "plot": 'ggplot' object. A group-to-group network plot.

• "table": data frame. An interactive matrix of the network.

• ⁠"network⁠: 'igraph' object used for creating the network plot.

• "data": data frame. A long table of the underlying data.

# Return a network plot

)

# Return a network plot - custom-specific colours
# Get labels of orgs and assign random colours
org_str <- unique(g2g_data$PrimaryCollaborator_Organization)

col_str <-
  sample(

    replace = TRUE
  )

# Create and supply a named vector to `node_colour`
names(col_str) <- org_str

g2g_data %>%
  network_g2g(node_colour = col_str)


# Return a network plot with circle layout
# Vary node colours and add org sizes
