表示没有“经典”热图的相关矩阵

Question

我正在对 complex.network 进行一些分析。 我已经计算了度相关矩阵，它看起来像这样：

data[1:5, 1:5] 

    1  2  3  4  5
1   6 19 11 16  5
2  19 10 16 12  6
3  11 16  7 11 10
4  16 12 11  5  9
5   5  6 10  9  8

我想 plot 它获得类似于此的东西：

我试过使用 ggplot 但结果并不令人满意，这是我的代码：

library(reshape2)
library(ggplot2)
data = melt(data) 
#The "melt" function was used to turn the matrix in a three column dataframe with columns named "Var1",
"Var2", and "value"

ggplot(data = data) +
theme_bw() +
geom_tile(aes(x = Var1, y = Var2, fill = value)) +
scale_fill_viridis(name = "") +
labs(x = "k2", y = "k1")

这就是我得到的：

有什么办法可以解决吗？

PS对不起，如果我不能直接发布图像，但我的声誉不够高

编辑：我把矩阵的dput() output 放在这里，如评论中所问：

Answer 1

你得到这些线是因为你有缺失值。 您的数据中未显示完整范围。 这是使用tidyr填充缺失值的一种方法

library(dplyr)
library(tidyr)

full_range <- function(x) seq(min(x), max(x))
data %>% 
  as.data.frame() %>% 
  tibble::rownames_to_column("Var1") %>% 
  pivot_longer(-Var1, names_to="Var2") %>% 
  mutate(across(Var1:Var2, as.numeric)) %>% {
    d <- .
    expand_grid(Var1=full_range(d$Var1), Var2=full_range(d$Var2)) %>% 
      left_join(d) %>% 
      replace_na(list(value=0))
  } %>% 
  ggplot() +
  theme_bw() +
  geom_tile(aes(x = Var1, y = Var2, fill = value)) +
  scale_fill_viridis_c(name = "") +
  labs(x = "k2", y = "k1")

看起来像这样
