r - 当我在 R 中绘制 NMF 等级调查时无法更改标签

Question

我正在对我拥有的数据集实施 R 分析。这是剧情

基本上我想更改数据标签。我设法更改了标题，但更改标签的常用脚本不起作用。基本上我的想法是：

#---Requested Edit with the Reprex
#Generating a random matrix
and.mat <- matrix(rnorm(2000),100,20)
#Shuffling the generated matrix 
Random.mat <- randomize(and.mat)
#non negative matrix factorization
real.estim <- nmf(and.mat,2:10,nrun=30,seed = 123456,.options='t')
#....................
shuffled.estim <- nmf(Random.mat,2:10,nrun=30,seed = 123456,.options='t')
plot(real.estim,shuffled.estim, main = 'NMF rank survey : Comparison between 
Real and Shuffled Data', 
xlab =' Real Data', ylab =' Shuffled Data')

先感谢您
