我产生了这个数字：
使用此代码：
replicate.plot = ggplot(data = replicate.plot.df, aes(factor(replicate), color = factor(haplotype)))
replicate.plot = replicate.plot + geom_boxplot(aes(fill = factor(haplotype),
lower = mean - std.dev, upper = mean + std.dev, middle = mean, ymin = mean - 3*std.dev, ymax = mean + 3*std.dev),
position = position_dodge(width = 0), width = 0.5, alpha = 0.5, stat="identity") + facet_wrap(~tissue, ncol = 4, scales = "free_x") +
scale_fill_manual(values = c("darkgreen","darkmagenta"),labels = c("haplotype.1","haplotype.2"),
name = "haplotype allele")+scale_colour_manual(values = c("darkgreen","darkmagenta"),
labels = c("haplotype.1","haplotype.2"),name = "haplotype allele")
因此，您可以看到我通过单倍型字段对框进行着色。我想要做的是有两组不同的颜色：一对是hap1和hap2，它们是基因型het，另一对是hap1和hap2，它们是基因型hom，并且具有这两个水平的传说。好。
1 个答案:
答案 0 :(得分：3)
为两个感兴趣的变量（单倍型和基因型）之间的相互作用创建一个新变量
replicate.plot.df$hapgeno<-interaction(replicate.plot.df$haplotype,
replicate.plot.df$genotype)
然后根据该变量着色
ggplot(data = replicate.plot.df, aes(factor(replicate))) +
geom_boxplot(aes(fill = hapgeno, lower = mean - std.dev, upper = mean + std.dev,
middle = mean, ymin = mean - 3*std.dev, ymax = mean + 3*std.dev),
position = position_dodge(width = .5), width = 0.5, alpha = 0.5, stat="identity") +
facet_wrap(~tissue, ncol = 3, scales = "free_x") +
scale_fill_manual(values = c("darkgreen","darkmagenta","lightgreen","magenta"),
labels = c("haplotype.1.het","haplotype.2.het","haplotype.1.hom","haplotype.2.hom"),
name = "haplotype allele")
