n_obs

Returns the number of observations of a vector or data.frame. It uses
<code><a href="https://vctrs.r-lib.org/reference/vec_size.html">vctrs::vec_size()</a></code> under the hood.

Provides a framework of tools to summarise, visualise, and explore
longitudinal data. It builds upon the tidy time series data frames used in the
'tsibble' package, and is designed to integrate within the 'tidyverse', and
'tidyverts' (for time series) ecosystems. The methods implemented include
calculating features for understanding longitudinal data, including
calculating summary statistics such as quantiles, medians, and numeric ranges,
sampling individual series, identifying individual series representative of a
group, and extending the facet system in 'ggplot2' to facilitate exploration of samples of data. These methods are
fully described in the paper "brolgar: An R package to Browse Over
Longitudinal Data Graphically and Analytically in R", Nicholas Tierney,
Dianne Cook, Tania Prvan (2020) <arXiv:2012.01619>.
