r - R基于行对的灵活条件格式

Question

我正在尝试根据标记的行中的值（对于实际）是否超过标记的相应行（即相同）中的值来更改bga 中某些单元格的颜色。那些超过的应该得到绿色背景，而那些低于的值应该得到红色背景。flextableActKPIPlanPlan

（在一个完美的世界中，无论单元格大于还是小于，我都可以更改背景颜色，这取决于我配置的列表来说明前进的方向，但接下来会出现。）

df <- structure(list(KPI = c("Quality", "Quality", "On Time", "On Time", 
"Attrition", "Attrition", "Growth 1", "Growth 1", "Growth 2", 
"Growth 2", "WCT", "WCT", "ROI", "ROI"), Type = c("Plan", "Act",

0.08, NA, NA, NA, NA, -0.2, -1.3, NA, NA), MAR = c(1, 1, 0.79, 
0.81, 0.05, 0.08, 0.1, 0.08, 116, 199, -0.7, -0.2, NA, NA), APR = c(1,

library(regulartable)
library(magrittr)

df %>% regulartable() %>% bg(i = ~ Type %in% "Act", j = 3:14, bg="#cceecc")

它产生的图像如下。我目前被卡住了，因为我无法弄清楚如何添加第二个条件，即无论该(value > lag(value))位置如何。有谁知道，还是我需要spread先知道gather？任何帮助将不胜感激。

df %>% regulartable() %>% bg(i = ~ Type %in% "Act" && (value > lag(value)), j = 3:14, bg="#cceecc")

我确信有一种更优雅的方法可以解决这个问题，如果有，我希望有人发布它。但与此同时，我找到了权宜之计。首先将 df 拆分为计划值和实际值，然后使用这些差异确定每个单元格的适当颜色：

library(gdata)

df %>% group_split(Type) -> plan.act
ifelse(plan.act[[1]][,3:14]-plan.act[[2]][,3:14]>=0, "#cceecc", "#eecccc") -> colorgrid 

这将为每个单元格创建一个红色/绿色列表：

> colorgrid
     JAN       FEB       MAR       APR       MAY       JUN       JUL       AUG       SEP       OCT NOV DEC
[1,] "#cceecc" "#eecccc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" NA  NA  NA 
[2,] NA        NA        "#cceecc" NA        NA        "#cceecc" NA        NA        "#eecccc" NA  NA  NA 
[3,] "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" "#cceecc" NA  NA  NA 
[4,] NA        NA        "#eecccc" NA        NA        "#eecccc" NA        NA        "#eecccc" NA  NA  NA 
[5,] NA        NA        "#cceecc" NA        NA        "#cceecc" NA        NA        "#cceecc" NA  NA  NA 
[6,] "#eecccc" "#eecccc" "#cceecc" "#eecccc" "#eecccc" "#cceecc" "#eecccc" "#cceecc" "#cceecc" NA  NA  NA 
[7,] NA        NA        NA        NA        NA        NA        NA        NA        NA        NA  NA  NA 

现在为 Plan 组的颜色创建另一个 df，然后绘制表格：

blankgrid <- colorgrid
blankgrid[!is.na(blankgrid)] <- NA_character_

df %>% regulartable() %>% bg(j = 3:14, bg=interleave(blankgrid,colorgrid))

从那里您可以添加更多灵活的优点以使表格更漂亮：

df %>% regulartable() %>% bg(j = 3:14, bg=interleave(blankgrid,colorgrid)) %>%
     merge_v(j=1) %>% border_inner_v(border = fp_border(color="gray", width=1))
