创建数据框的子集以指示 geom_ribbon 中的限制

Question

我试图在图中的两条线之间填充，但经过多次试验后，我仍然无法弄清楚如何在代码中显示我需要着色的特定区域。

这是我的数据集：

high

Time	Trat	mean	sd	level
T1	HC	27.26	6.19	high
T1	Control HC	28.22	1.82	high
T1	HCc	26.39	6.19	high
T2	HC	32.81	0.84	high
T2	Control HC	30.10	2.58	high
T2	HCc	30.88	0.84	high
T3	HC	35.15	3.93	high
T3	Control HC	32.60	0.75	high
T3	HCc	33.91	3.93	high
T4	HC	38.60	3.50	high
T4	Control HC	29.66	4.81	high
T4	HCc	37.14	3.50	high
T5	HC	41.71	1.47	high
T5	Control HC	29.97	4.75	high
T5	HCc	39.78	1.47	high
T6	HC	41.07	0.32	high
T6	Control HC	27.04	4.79	high
T6	HCc	37.73	0.32	high
T7	HC	43.55	0.71	high
T7	Control HC	25.48	4.75	high
T7	HCc	40.32	0.71	high
T8	HC	45.71	2.62	high
T8	Control HC	24.13	4.61	high
T8	HCc	41.33	2.62	high
T9	HC	47.57	1.65	high
T9	Control HC	23.23	5.44	high
T9	HCc	42.12	1.65	high
T10	HC	51.53	4.40	high
T10	Control HC	24.69	6.81	high
T10	HCc	46.09	4.40	high

这是我的代码：

（我发布了完整的代码以备不时之需，但请忽略与问题没有直接关系的部分）。

ggplot(high, aes(Time, mean, color=Trat,group = Trat))+
geom_line( aes( linetype=Trat, color=Trat), size=1.5, na.rm=T)+
    labs(x = ("Time (days)"), y = bquote("Clorophyll-a"~ (µg.L^-1))) +
  scale_x_discrete(breaks=c("T1", "T2","T3", "T4", "T5","T6","T7","T8","T9","T10"),labels=c("1","2","3","4","5","6","7","8","9","10"))+
  theme_classic(base_size = 15)+
  theme(plot.title = element_text(hjust = 0.5))+
  theme(legend.position="right")+
  theme(legend.title = element_blank())+
  guides(col = guide_legend(nrow = 2))+
  scale_color_grey()+
  geom_errorbar(aes(ymin=mean-sd, ymax=mean+sd), width=1, position=position_dodge(.01))+
  guides(colour=guide_legend(nrow=3))+
  geom_ribbon(aes(x=Time, ymax=x.upper, ymin=x.lower), fill="gray", alpha=.5)

我需要将阴影区域放置在 HC 和 HCc 线之间。 .

如何在代码中显示上限为HC均值，下限为HCc均值？

我用这些值创建了分离向量，但代码产生错误。

我认为您需要将不同的数据框以宽格式传递到功能区：

ggplot(high, aes(Time, mean))+
geom_line( aes( linetype=Trat, color=Trat, group = Trat), size=1.5, na.rm=T)+
    labs(x = ("Time (days)"), y = bquote("Clorophyll-a"~ (µg.L^-1))) +
  scale_x_discrete(breaks=c("T1", "T2","T3", "T4", "T5","T6","T7","T8","T9","T10"),
                   labels=c("1","2","3","4","5","6","7","8","9","10"))+
  theme_classic(base_size = 15)+
  theme(plot.title = element_text(hjust = 0.5))+
  theme(legend.position="right")+
  theme(legend.title = element_blank())+
  guides(col = guide_legend(nrow = 2))+
  scale_color_grey()+
  geom_errorbar(aes(ymin=mean-sd, ymax=mean+sd,
                    color=Trat,group = Trat), 
                width=1, position=position_dodge(.01))+
  guides(colour=guide_legend(nrow=3))+
  geom_ribbon(data = tidyr::pivot_wider(high,
                                        id_cols = c("Time", "Trat"), 
                                        names_from = "Trat", 
                                        values_from = c("mean", "sd")),
              aes(y = 1, ymax=mean_HCc, ymin=mean_HC, color = "HC", group = "HC"), 
              fill="gray", alpha=.5)

创建数据框的子集以指示 geom_ribbon 中的限制

Create subset of data frame to indicate limits in geom_ribbon
