如何调整热图以显示所有内容?
How can I adjust the heatmap to show everything?
我的热图将元素标签剪掉了,我根本不想让它们显示在底部。我该如何调整它以使其适合所有内容?此外,密钥占用了太多 space,但当我使其小于 1 时,密钥和标题就会消失。
heatmap.2( x=correlation_mat,
dendrogram="column",
keysize = 1,
key.title = NA,
key.ylab = NA,
density.info = "none",
trace = "none",
Colv = "Rowv",
scale = "none",
col = rev(colorRampPalette(brewer.pal(10, "RdBu"))(256)),
main = "Correlations of Thickness")
为此您需要 gplots 和 RColorBrewer 库。
您可以使用带有两个值的附加 margins
参数来扩大页边距。
以下示例使用随机数据:
library("gplots")
library("RColorBrewer")
## sample data
x <- matrix(rnorm(1000), nrow=10)
## random lables
dimnames(x) <- list(
replicate(10, paste(sample(letters, 10, replace=TRUE), collapse="")),
replicate(100, paste(sample(letters, 10, replace=TRUE), collapse=""))
)
correlation_mat <- cor(x)
heatmap.2(x=correlation_mat,
dendrogram="column",
keysize = 1,
key.title = NA,
key.ylab = NA,
density.info = "none",
trace = "none",
Colv = "Rowv",
scale = "none",
col = rev(colorRampPalette(brewer.pal(10, "RdBu"))(256)),
main = "Correlations of Thickness",
margins = c(8, 8))
完全删除底部标签margins = c(1, 8)
对我有用。
