我如何生成ASCII“图形输出”？从R？ [英] How can I generate ascii "graphical output" from R?

问题描述

我相信R可以使用软件包。当前，它包括散点图，折线图，密度图，acf和条形图。

从在线帮助中，

 > txtplot（汽车[，1]，汽车[，2]）
 + ---- + ------------ ++ ------------ + ----------- + ------------ +-+ 
 120 + * +

 100 + +

I believe R can generate stem-and-leaf for ascii histograms, and scatter plots using this code from Matt Shotwell.

Can it also generate ASCII based line graphs, like this from GNUPlot?

解决方案

You should look at the fairly recent txtplot package. Currently, it includes scatterplot, line plot, density plot, acf, and bar chart.

From the online help,

> txtplot(cars[,1], cars[,2])

    |                                                          |
100 +                                                          +
    |                                                     * *  |
 80 +                           *         *                    +
