spark

This is an R port of spark.sh.

The spark.sh wiki has some cool usage examples.

Installation

Install it from github, with the devtools package:

devtools::install_github("gaborcsardi/spark")
library(spark)

Enhancements

The R package has some improvements compared to the original shell implementation.

Scaling

The length of the spark line can be fitted to the width of the teminal window:

spark(lynx, width = "auto")
##> ▁▁▂▄▆▇▃▁▁▁▄▄▂▁▁▁▁▃▃▁▁▁▂▄▃▁▁▁▂▆▆▁▁▁▂▃▂▁▁▁▂▄▅▂▁▁▁▁▃▅▁▁▁▂▇█▄▁▁▂▅▅▅▂▁▁▁▂▄▄▂▁▂▃▄

Matrices

Matrices can be plotted row-wise:

spark(t(EuStockMarkets), width="auto", common_scale = FALSE)
