首先，通过代码绘制三元图，我们需要导入Ternary包。1library(Ternary) 最简单的三元图绘制方式，就是通过图下的代码，生成一个最基本的三元图。1TernaryPlot() 运行上述代码，将得到如下所示的图片。 当然，我们需要结合实际的需求，对这个简单的三元图加以个性化修改。首先，本文所用到的...
RGBA color values are an extension of RGB color values with an Alpha channel - which specifies the opacity for a color. An RGBA color value is specified with: rgba(red,green,blue, alpha) The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (not transparent at all): ...
("ringing") due to filtering. The value 235 accommodates a maximal black-to-white overshoot of 255 − 235 = 20, or 20 / (235 − 16) = 9.1%, which is slightly larger than the theoretical maximal overshoot (Gibbs phenomenon) of about 8.9% of the maximal step. The toe-room is ...
