r - 基本 R 图的颜色已更改 - 我可以恢复到旧调色板吗？

Question

我注意到我的 base R 图中的颜色发生了变化。请看例如我的绘图“before”(以前的 R 版本)和“now”(当前 R 版本，4.0.0)上的红色。

我能做些什么来重置任何可能的设置(例如，par() 等)以将颜色恢复为正常颜色？

Answer 1

颜色的差异是由于 R 4.0.0 中的默认调色板发生了变化。您可以使用 palette("R3") 恢复到旧颜色。

来自release news :

The palette() function has a new default set of colours (which are less saturated and have better accessibility properties). There are also some new built-in palettes, which are listed by the new palette.pals() function. These include the old default palette under the name "R3".

R 4.0.0 中的默认调色板:

palette()
# [1] "black"   "#DF536B" "#61D04F" "#2297E6" "#28E2E5" "#CD0BBC" "#F5C710" "gray62" 

恢复到旧的默认调色板，“R3”:

palette("R3")
palette()
# [1] "black"   "red"     "green3"  "blue"    "cyan"    "magenta" "yellow"  "gray"   

再次更改为当前默认值:

palette("default")
# or
palette("R4")

palette()
# [1] "black"   "#DF536B" "#61D04F" "#2297E6" "#28E2E5" "#CD0BBC" "#F5C710" "gray62"
