在ComplexHeatmap包中,添加decorate_annotation到垂直连接的upset图中,可以按照以下步骤进行设置。
首先,需要安装ComplexHeatmap包:
install.packages("ComplexHeatmap")
存储需要使用的数据data和类别标签categories,并载入ComplexHeatmap包:
library(ComplexHeatmap)
data = matrix(rnorm(100, 10, 1), ncol = 10)
colnames(data) = paste0("Category", 1:10)
categories = c("A", "A", "B", "C", "C", "C", "D", "D", "E", "E")
接下来,可以通过upset_plot()函数创建upset图,并设置decorate_annotation参数:
upset = upset_plot(data,
categories = categories,
nsets = 5,
order_by = "freq",
empty_size = 0.5,
main = "Upset plot")
其中decorate_annotation可以设置为一个ggplot对象,以改变注释的外观和位置。下面的示例将annotate()函数添加到decorate_annotation中,以在图中添加注释:
decorate_annotation = ggplot2::annotate("text",
x = 2,
y = 3.5,
label = "My annotation",
size = 4,
color = "black")
upset = upset_plot(data,
categories = categories,
nsets = 5,
order_by = "freq",
empty_size = 0.5,
main = "Upset plot",
decorate_annotation = decorate_annotation)
最后,可以使用draw()函数将upset图绘制出来:
draw(upset)
