“对“哪个"不合逻辑"的争论是什么? FactoMineR MCA是什么意思? [英] What does "argument to 'which' is not logical" mean in FactoMineR MCA?

问题描述

我正在尝试使用FactoMineR在数据表上运行MCA.它仅包含0/1个数字列，其大小为200.000 * 20.

I'm trying to run an MCA on a datatable using FactoMineR. It contains only 0/1 numerical columns, and its size is 200.000 * 20.

require(FactoMineR)
result <- MCA(data[, colnames, with=F], ncp = 3)

我收到以下错误:

其中(unlist(lapply(listModa，is.numeric)))的错误: 哪个"的参数不合逻辑

Error in which(unlist(lapply(listModa, is.numeric))) : argument to 'which' is not logical

我真的不知道该怎么办.然后，我尝试将每一列都转换为字符，然后一切正常.我认为这可能对其他人有用，也许有人可以向我解释该错误；)

I didn't really know what to do with this error. Then I tried to turn every column to character, and everything worked. I thought it could be useful to someone else, and that maybe someone would be able to explain the error to me ;)

欢呼

推荐答案

没有进一步的输入就很难分辨，但是您可以做的是:

It's difficult to tell without further input, but what you can do is:

• 找到发生错误的功能(通过traceback())，

• 设置一个断点并对其进行调试:

• Find the function where the error occurred (via traceback()),

• Set a breakpoint and debug it:

trace(tab.disjonctif, browser)

我做了以下操作(离线)来找到tab.disjonctif的名称:

I did the following (offline) to find the name of tab.disjonctif:

• 在CRAN镜像上在GitHub上找到包
• 搜索会给出错误

• Found the package on the CRAN mirror on GitHub
• Search for that particular expression that gives the error
