Draw a sparkline line graph with Braille characters.

You might want to avoid sparklines on non-UTF-8 systems, because they do not look good. You can use is_utf8_output() to test for support for them.

Usage

spark_line(x)

Arguments

x

A numeric vector between 0 and 1

Details

x <- seq(0, 1, length = 10)
