Plot the trailing-window rate (issue_rate_tbl()'s rate column - see its metric param for whether that's issues or comments per repo-month) over time, one line per popularity stratum.

Plot the trailing-window rate (issue_rate_tbl()'s rate column - see its metric param for whether that's issues or comments per repo-month) over time, one line per popularity stratum.

Usage

plot_activity(rate_tbl, src_name = NULL, start_year = NULL)

Arguments

rate_tbl

As returned by issue_rate_tbl() - its metric, window, contrib_threshold, and source_name attributes are read straight off it, the first three to label the y-axis and source_name to annotate the plot panel directly (top-right corner), rather than needing to be passed in again.

src_name

Name of source of rate_tbl to be added as plot annotation if specified.

start_year

Optional year (e.g. 2018) to start the plotted window from; NULL (default) plots rate_tbl's full window. Only crops the display - rate_tbl isn't refetched, so this can't extend the window beyond what issue_rate_tbl() was already called with.

Value

A ggplot object.

Examples

if (FALSE) { # \dontrun{
rate_tbl <- issue_rate_tbl (issue_authors_tbl, repo_tbl, "pypi")
plot_activity (rate_tbl)
} # }
