R語言學(xué)習(xí)記錄：畫圖的顏色設(shè)置
數(shù)據(jù)一般分為：
類別變量（categorical variable）以及連續(xù)變量（continuous variable）
將變量值映射為顏色， 可以分為如下四種情況：
無序的分類變量；qualitative
有序的分類變量，僅有大小次序，沒有正反；sequential
有序的分類變量，有正有反；diverging
連續(xù)數(shù)值變量。continuous
The first set of color palettes are?sequential?palettes and are suitable for a variable that has ordinal meaning: temperature, precipitation, etc. The second set of palettes are?qualitative?palettes and suitable for qualitative or categorical data. Finally, the third set of palettes are?diverging?palettes and can be suitable for variables that take both negative and positive values like changes in groundwater level.
Two types of?scale?functions can be used to use these palettes:
scale_*_distiller()?for a continuous variablescale_*_brewer()?for a discrete variable
To use a specific color palette, you can simply add?palette = "palette name"?inside?scale_fill_distiller(). The codes below applies “Spectral” as an example.
