这是非常大数据的一小部分
df<- structure(list(A = c(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0.68906, 0, 0, 0, 0, 0, 0, 0, 0, 0.13597, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0), B = c(0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0.40001, 0, 0, 0, 0, 0.69718, 0, 0, 0, 0, 0, 0, 0,
0, 0.090752, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0), C = c(0, 0, 0, 0,

), D = c(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0.86419, 0, 0, 0, 0.3845,

0, 0, 0, 0.38499, 0, 0, 0, 0, 0.69064, 0, 0, 0.14596, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0), F = c(0, 0, 0, 0, 0,
0, 0, 0, 0, 1.0954, 0.74426, 0, 0, 0, 0.37715, 0, 0, 0, 0, 0.68884,

0, 0), G = c(0, 0, 0, 0, 0, 0, 0, 0, 0, 1.0985, 0.66651, 0, 0,
0, 0, 0, 0, 0, 0, 0.68861, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1.1812,
0, 0, 0, 0, 0, 0, 0, 0)), .Names = c("A", "B", "C", "D", "E",
"F", "G"), class = "data.frame", row.names = c(NA, -39L))
我想要的是当数据中有很多零时以更有压力的方式显示值
我如何绘制它是这样的
eucl_dist=dist(df,method = 'euclidean')
hie_clust=hclust(eucl_dist,method = 'complete')
my_palette <- colorRampPalette(c( "green", "yellow", "red"))(n = 1000)
heatmap.2(mydata, scale = c("none"), Colv=F, Rowv=as.dendrogram(hie_clust),
xlab = "X", ylab = "Y", key=TRUE, keysize=1.1, trace="none",
density.info=c("none"), margins=c(4, 4), col=my_palette, dendrogram="row")
但正如你所看到的,在这个小例子中,零主宰了我的情节,当它非常大时,什么都看不到。我也不能改变值的位置
