修复R包中的错误“；lcmm"；-&引用；参数主题必须是数字“quot；

尝试在“lcmm”（我第一次使用这个包）中运行初始的1类模型

我的代码是：

> lcga1 <- hlme(ActMed ~ time_rec, subject = 'person_ID', ng = 1, data = data)

不用担心，对吧？根据我在这里和包文档中看到的其他问题，这是由于ID变量不是数字。但当我检查它是否是（因为它应该是）：

如果我试图强迫它：

> data$person_ID <- as.numeric(data$person_ID)
> lcga1 <- hlme(ActMed ~ time_rec, subject = 'person_ID', ng = 1, data = data) 
Be patient, hlme is running ... 
Error in hlme(ActMed ~ time_rec, subject = "person_ID", ng = 1, data = data) : 
  The argument subject must be numeric

---

>data$person\u ID lcga1尝试删除
subject='person\u ID'
中的引号。
> is.numeric(data$person_ID)
[1] TRUE

> data$person_ID <- as.numeric(data$person_ID)
> lcga1 <- hlme(ActMed ~ time_rec, subject = 'person_ID', ng = 1, data = data) 
Be patient, hlme is running ... 
Error in hlme(ActMed ~ time_rec, subject = "person_ID", ng = 1, data = data) : 
  The argument subject must be numeric
