我在 R 中有这个颜色向量：
"#88FF00" "#54FF00" "#FFFF00" "#13FF00" "#50FF00" "#87FF00" "#FDFB02" "#B8FF00" "#6DFF00"
"#ECFF00" "#CBFF00" "#EDFF00" "#39FF00" "#B7FF00" "#75FF00" "#65FF00" "#C2FF00" "#25FF00"
"#9AFF00" "#E6FF00" "#58FF00" "#E5CA1A" "#DEFF00" "#9AFF00" "#21FF00" "#35FF00" "#3AFF00"
"#D0912F" "#FF0000" "#F7EF08" "#40FF00" "#DA7325" "#D8B027" "#DAFF00" "#55FF00" "#F8F007"
"#46FF00" "#69FF00" "#B8FF00" "#37FF00" "#32FF00" "#60FF00" "#7CFF00" "#00FF00" "#50FF00"
"#F3E60C" "#DFBE20" "#7FFF00" "#F7EF08" "#99FF00" "#13FF00" "#DA7325" "#13FF00"
我想按此顺序绘制它们，例如热图。我一直在玩弄图像功能，但颜色被重新排序，甚至被图像功能修改。
我尝试的代码如下，当 cols 是上面提到的颜色向量时：
image(1:nrow(expressionOrdered), 1:ncol(expressionOrdered), as.matrix(expressionOrdered), col= cols,xlab="",ylab="")
