r - 如何在ggplot中将手动色标传递给geom_smooth？

Question

我的数据看起来像这样:

# A tibble: 6 x 4
    CFU         strain   diltn order
  <dbl>         <fctr>   <dbl> <dbl>
1   0.0 M12-611025 (0) 5.89279     1
2   1.0 M12-611025 (0) 5.19382     1
3   0.0 M12-611025 (0) 4.49485     1
4   0.5 M12-611025 (0) 3.79588     1
5   1.0 M12-611025 (0) 3.09691     1
6   7.0 M12-611025 (0) 2.39794     1

我有 16 种不同的“应变”，只想在我的图形上绘制一个子集以及使用 geom_smooth 画一条线。我已经实现了如下:

lines1 <- c("M12-611025 (0)" = "solid",
            "M12-611025 (0) HI" = "dashed",
            "M12-611025 (300)" = "solid",
            "M12-611025 (300) HI" = "dashed",
            "M12-611025 (700)" = "solid",
            "M12-611025 (700) HI" = "dashed",
            "M12-611025 (1100)" = "solid",
            "M12-611025 (1100) HI" = "dashed")

ggplot(data = (subset(data,
  strain %in% c("M12-611025 (0)", "M12-611025 (0) HI",
                "M12-611025 (300)", "M12-611025 (300) HI",
                "M12-611025 (700)", "M12-611025 (700) HI",
                "M12-611025 (1100)", "M12-611025 (1100) HI"))),
  (aes(x = diltn, y = CFU, colour = factor(strain),
       fill = factor(strain), linetype = factor(strain)))) +
  geom_smooth(se = F, span = 1) +
  geom_point(shape = 21, colour = "black", size = 2, stroke = 1) +
  scale_y_continuous(limits = c(-1, 120))+
  scale_x_continuous(breaks = c(0, 1, 2, 3, 4),
                     labels = c(0, 10, 100, 1000, 10000),
                     limits = c(1, 4))+
  annotation_logticks(base = 10, sides = "b", scaled = TRUE) +
  theme(axis.line = element_line(colour = "black",
                                 size = 1,    
                                 linetype = "solid")) +
  ggtitle("RPM Test M12 - 611025") + 
  xlab(expression(paste("Dilution "))) + 
  ylab("CFU") +
  scale_linetype_manual(values = lines1)

这里的关键是我想用“HI”作为虚线绘制条纹，将其他线条绘制为实线，这给了我:



然后我想定义我自己的配色方案，以便相同的菌株具有相同的色点和线条，但线条为“HI”版本的虚线。我试过这个:

cols1 <- c("M12-611025 (0)" = "blue",
           "M12-611025 (0) HI" = "blue",
           "M12-611025 (300)" = "#ff9700",
           "M12-611025 (300) HI" = "#ff9700",
           "M12-611025 (700)" = "#33d100",
           "M12-611025 (700) HI" = "#33d100", 
           "M12-611025 (1100)" = "#fe0000",
           "M12-611025 (1100) HI" = "#fe0000")

M12_611025 + scale_fill_manual(values = cols1)

这会改变点而不是线，我不知道如何使线与点的颜色相同？

行使用 color美学和形状点 21 使用 fill美学(对于内部颜色，轮廓也是 color 美学)。因此，在您的情况下，您需要同时更改 fill和 color规模:

M12_611025 + 
  scale_fill_manual(values = cols1) +
  scale_color_manual(values = cols1)
