我是R的新手，我目前正在尝试制作一张表格，向我显示2天之间的变化，并且一旦计算出该变化（如果为负，则海变成红色，如果没有，则变为绿色）

答案 0 :(得分：0)

当前，color = ifelse('VARIACION'< -0,'#ed1c16','#0ca649')正在评估字符串VARIACION是否小于0。虽然这不是一个特别有意义的问题，但R确实将其评估为FALSE（在您所有的情况下），因此将绿色打印为结果。

更一般地说，在这种情况下，您不想使用ifelse()。请改用类似formatStyle('VARIACION', color = styleInterval(0, c("red", "green"))的名称。

此处的键是styleInterval()，它定义间隔的切点和颜色。当您放置一个切割点（例如0）和两种颜色时，它将使用第一种颜色在切割点之前，第二种在切割点之后。但是，您可以有多个间隔（切点> 1）。您只需要一种颜色即可，但切点要多（例如，在下面的示例中尝试使用color = styleInterval(c(0,300000), c("red", "green","blue")))之类的颜色）。

以下是从https://rstudio.github.io/DT/functions.html修改而来的工作示例：

library(DT)
m = cbind(matrix(rnorm(60, 1e5, 1e6), 20), runif(20), rnorm(20, 100))
m[, 1:3] = round(m[, 1:3])
m[, 4:5] = round(m[, 4:5], 7)
colnames(m) = head(LETTERS, ncol(m))
head(m)

datatable(m) %>% 
  formatCurrency(c('A', 'C')) %>% 
  formatStyle('A',  color = styleInterval(0, c("red", "green")))

请进一步注意，使用ifelse()的更正确的实现仍然会失败，因为它返回向量，并且color选项不需要向量（因此，它不会引发错误，也不会绘制） 。同样，请不要在此处使用ifelse()。

#this fails
datatable(m) %>% 
  formatCurrency(c('A', 'C')) %>% 
  formatStyle('A',  color = ifelse(m[,"A"] < 0, "red", "green"))
