browse_data: Browse a data frame in the terminal

In termr: Modern Reactive Terminal Applications with Data Workflows

Browse a data frame in the terminal

Description

browse_data() opens an interactive viewer for a data frame: summary metrics, a virtualised table (fast for millions of rows), information about the selected column, search across all columns, sorting, and row details. data_browser() builds the same app without running it, e.g. to customise or test it.

Usage

browse_data(data, title = deparse(substitute(data)), ...)

data_browser(data, title = deparse(substitute(data)), ...)

Arguments

data	A data frame or matrix.
title	Title shown at the top (defaults to the expression).
...	Passed to data_table() (e.g. formatters, columns).

Details

Keys: arrows / Page Up / Page Down move the cell cursor; / focuses the search box (Enter applies it, Escape in the box clears it); s sorts by the current column (again: descending); r resets sorting and search; Enter shows the row; q quits.

Value

browse_data() returns NULL invisibly; data_browser() returns an App.

Examples

viewer <- data_browser(mtcars)
pilot <- test_app(viewer, 100, 30)
pilot$press("s")
pilot$stop()
if (interactive()) browse_data(mtcars)
