如何在R中的热图中重叠因子（二进制）和连续变量
how to overlap factor(binary) & continuous variables in heat map in R
以下代码改编自https://simplystatistics.org/2019/08/28/you-can-replicate-almost-any-plot-with-ggplot2/
我正在尝试将 rate 连续变量的当前热图与 Vaccine 因子（二进制）变量重叠。
2 个问题：
1-当 Vaccine ==1 和灰色（“gray95”）时，我想将热图的颜色转换为更粉红色（“palevioletred1”）而不是垂直线否则 (Vaccine=0).
2-我在 gglot 中包含了 colour = Vaccine，以便在 Vaccine ==1 时显示粉红色的条形轮廓，但是通过包含它，我没有发现任何区别。
关于如何执行 1 或 2 的任何想法？提前致谢。
代码如下：

annotate(geom = "text", x = 1963, y = 50.5,
label = "Vaccine introduced", size = 3, hjust = 0)
选项 2
您可以使用 scale_color_manual。只需确保您的 Vaccine 列确实是水平为 "0" 和 "1"
的因子变量
dat %>% mutate(state = reorder(state, desc(state))) %>%
ggplot(aes(year, state, fill = rate)) +
geom_tile(aes(color = Vaccine), size = 0.35) +
scale_color_manual(values = c('0' = "white", '1' = "pink")) +
scale_x_continuous(expand = c(0,0)) +
scale_fill_gradientn(colors = jet.colors(16), na.value = 'white') +
geom_vline(xintercept = 1963, col = "black") +
theme_minimal() +
theme(panel.grid = element_blank()) +
coord_cartesian(clip = 'off') +
ggtitle(the_disease) +
ylab("") +
xlab("") +
theme(legend.position = "bottom", text = element_text(size = 8)) +
annotate(geom = "text", x = 1963, y = 50.5, label = "Vaccine introduced",
size = 3, hjust = 0) +
guides(color = guide_legend(override.aes = list(fill = "white")))
就其价值而言，我更喜欢选项 1
