在 R 编程中创建围绕 RGB 比例的红色光谱聚集的一系列连续颜色 – heat.colors()函数

在 R 编程中，我们可以使用 heat.colors() 函数来创建一系列围绕红色光谱的连续颜色。这些颜色使用了 RGB 颜色比例，从而让我们能够控制颜色的深浅和饱和度。

语法

heat.colors(n)

• n: 要创建的颜色数量。默认为 64。

示例

# 创建 8 种颜色的连续光谱
heat.colors(8)

# 创建 16 种颜色的连续光谱
heat.colors(16)

# 创建 32 种颜色的连续光谱
heat.colors(32)

# 创建 64 种颜色的连续光谱
heat.colors(64)

# 创建 128 种颜色的连续光谱
heat.colors(128)

# 创建 256 种颜色的连续光谱
heat.colors(256)

输出结果

上述示例中，我们使用 heat.colors() 函数创建了不同数量的连续光谱。输出结果如下：
