假设我有两个对称矩阵:
library(Matrix)
set.seed(123)
s1<-forceSymmetric(matrix(round(rnorm(25),2),5))
colnames(s1)<-LETTERS[1:5]
rownames(s1)<-LETTERS[6:10]
diag(s1)<-1
s2<-forceSymmetric(matrix(round(rbinom(25,25,0.3),2),5))
colnames(s2)<-LETTERS[1:5]
rownames(s2)<-LETTERS[6:10]
diag(s2)<-1
s1
# 5 x 5 Matrix of class "dsyMatrix"
# A B C D E
# F 1.00 1.72 1.22 1.79 -1.07
# G 1.72 1.00 0.36 0.50 -0.22
# H 1.22 0.36 1.00 -1.97 -1.03
# I 1.79 0.50 -1.97 1.00 -0.73
# J -1.07 -0.22 -1.03 -0.73 1.00
s2
# 5 x 5 Matrix of class "dsyMatrix"
# A B C D E
# F 1 6 8 7 9
# G 6 1 5 9 8
# H 8 5 1 10 9
# I 7 9 10 1 1
# J 9 8 9 1 1
我想要生成一个单一的热图,其中上对角线及其图例基于矩阵s1,而下对角线及其图例基于矩阵s2。这是我可以找到的类似图片:
答案 0 :(得分:0)
获取对角线
reverse = s1[,ncol(s1):1]
diag(reverse) = 0
reverse[lower.tri(reverse, diag = FALSE)] <- 0
upper = reverse[,ncol(reverse):1]
降低对角线
reverse1 = s2[,ncol(s2):1]
diag(reverse1) = 0
reverse1[upper.tri(reverse1, diag = FALSE)] <- 0
upper1 = reverse1[,ncol(reverse1):1]
是时候添加它们了。
merged = as.matrix(upper+upper1)
merged
A B C D E
F 1.00 1.72 1.22 1.79 0
G 1.72 1.00 0.36 0.00 8
H 1.22 0.36 0.00 10.00 9
I 1.79 0.00 10.00 1.00 1
J 0.00 8.00 9.00 1.00 1
绘制它。
