r - 如何在 .Rprofile 中设置调色板

Question

我想在 R 启动时更改调色板。因此我将以下源代码复制到我的 .Rprofile

palette(c(
  "#2e3436"   # (Aluminium 6)
  , "#ef2929" # (Scarlet Red 1)
  , "#73d216" # (Chameleon 2)
  , "#3465a4" # (Sky Blue 2)
  , "#fcaf3e" # (Orange 1)
  , "#ad7fa8" # (Plum 1)
  , "#babdb6" # (Butter 1)
  , "#babdb6" # (Aluminium 3)
))

启动 R 时会显示以下消息:

Error: Could not fine the function 'palette'

是否无法在启动时更改调色板？

Answer 1

来自 ?Startup

Note that when the site and user profile files are sourced only the 'base' package is loaded, so objects in other packages need to be referred to by e.g. 'utils::dump.frames' or after explicitly loading the package concerned.

因此调用 grDevices::palette() 而不是 palette()。 (需要调用 dev.off() 来消除启动后出现的空白图形窗口。)

grDevices::palette(c(
  "#2e3436"   # (Aluminium 6)
  , "#ef2929" # (Scarlet Red 1)
  , "#73d216" # (Chameleon 2)
  , "#3465a4" # (Sky Blue 2)
  , "#fcaf3e" # (Orange 1)
  , "#ad7fa8" # (Plum 1)
  , "#babdb6" # (Butter 1)
  , "#babdb6" # (Aluminium 3)
))

grDevices::dev.off()
