summarise.metric_graph_data

summarise

Creates summaries, while keeps the spatial positions.

Facilitates creation and manipulation of metric graphs, such as street or river networks. Further facilitates operations and visualizations of data on metric graphs, and the creation of a large class of random fields and stochastic partial differential equations on such spaces. These random fields can be used for simulation, prediction and inference. In particular, linear mixed effects models including random field components can be fitted to data based on computationally efficient sparse matrix representations. Interfaces to the R packages 'INLA' and 'inlabru' are also provided, which facilitate working with Bayesian statistical models on metric graphs.

summarise.metric_graph_data function

<dl><dt>.data</dt>
<dd>The data list or <code><a href="https://tibble.tidyverse.org/reference/tibble.html">tidyr::tibble</a></code> obtained from a metric graph object.</dd>
<dt>...</dt>
<dd>Additional parameters to be passed to <code><a href="https://dplyr.tidyverse.org/reference/summarise.html">dplyr::summarise()</a></code>.</dd>
<dt>.include_graph_groups</dt>
<dd>Should the internal graph groups be included in the grouping variables? The default is <code>FALSE</code>. This means that, when summarising, the data will be grouped by the internal group variable together with the spatial locations.</dd>
<dt>.groups</dt>
<dd>A vector of strings containing the names of the columns to be additionally grouped, when computing the summaries. The default is <code>NULL</code>.</dd></dl>
