BrailleR (version 0.30.2)

history: View the history of the current workspace

Description

A substitute for the history function from the utils package.

Usage

history(max.show = 25, reverse = FALSE, pattern, ...)

Arguments

max.show

The maximum number of lines to show. Inf will give all of the currently available history.

reverse

logical. If true, the lines are shown in reverse order. Note: this is not useful when there are continuation lines.

pattern

A character string to be matched against the lines of the history. When supplied, only unique matching lines are shown.

Arguments to be passed to grep when doing the matching.

Value

Nothing is returned to the workspace. This function exists for the creation and viewing of the temporary file that holds the list of commands issued in the current workspace.

Details

This function exists because the standard history function in the utils package opens the internal pager that cannot be used by a blind person's screen reading software.
