【问题描述】:
R 中的许多函数都提供了某种控制台输出(例如 NbClust() 等)。有没有办法在不查看输出的情况下检索某些输出(例如某个整数值)?从控制台读取的任何方式?
想象一下,package manual 中提供的示例代码的输出如下所示:
[1] "Frey index : No clustering structure in this data set"
*** : The Hubert index is a graphical method of determining the number of clusters.
In the plot of Hubert index, we seek a significant knee that corresponds to a
significant increase of the value of the measure i.e the significant peak in Hubert
index second differences plot.
*** : The D index is a graphical method of determining the number of clusters.
In the plot of D index, we seek a significant knee (the significant peak in Dindex
second differences plot) that corresponds to a significant increase of the value of
the measure.
*******************************************************************
* Among all indices:
* 1 proposed 2 as the best number of clusters
* 2 proposed 4 as the best number of clusters
* 2 proposed 6 as the best number of clusters
* 1 proposed 7 as the best number of clusters
***** Conclusion *****
* According to the majority rule, the best number of clusters is 4

如何从上述输出的最后一行检索值 4?
【问题讨论】:
-
否,
x$Best.nc返回一个列表,其中包含每个索引各自的“簇数”值。但这不是我感兴趣的,我想取回最后一行的值…… -
@zx8754 如上所述,我真的在寻找一种从控制台输出中检索信息的方法,不仅适用于
NbClust(),而且通常适用于 R 中的函数生成的任何输出 -
是的,这行得通!谢谢@zx8754 谢谢你还指出使用控制台输出并不常见,你想把它作为这个问题的答案吗?
