R 下三角相关热图
我试图在R中产生一个低三角形的成对关联热图 以下是数据:R 下三角相关热图,r,ggplot2,heatmap,R,Ggplot2,Heatmap,我试图在R中产生一个低三角形的成对关联热图 以下是数据: set.seed(1) mat <- matrix(rnorm(6*10),ncol=6,nrow=10) colnames(mat) <- c("s.-.+.1","s.-.+.2","s.-.+.3","s.+.-.1","s.+.-.2","s.+.-.3") 这给了我: 因此,彩色元素分散在整个区域,而不是局限于较低的三角形 知道问题出在哪里吗?嗯,我复制了你的剧本,这是我的情节 换衣服 ggplot(cor.mat
set.seed(1)
mat <- matrix(rnorm(6*10),ncol=6,nrow=10)
colnames(mat) <- c("s.-.+.1","s.-.+.2","s.-.+.3","s.+.-.1","s.+.-.2","s.+.-.3")
这给了我:

它似乎起作用了。我认为您在ggplot函数中使用了错误的变量:cor.mat.df应该是cor.df。
