R语言小白一枚，在运行多重插补时出现了一点问题求高手解答，脚本如下：
library(rms)
data.raw<-read.csv("C:/Users/chen/Desktop/3.24/3.24.csv",head=T,sep=',',stringsAsFactors = FALSE )
data.deal<-data.raw

(data<-data.frame)
library(mice)
impdatas<-mice(data.raw,seed=2016,m=5)#运行至这里时会提醒 iter imp variable  1   1  GluError in solve.default(xtx + diag(pen)) :   system is computationally singular: reciprocal condition number = 3.49747e-19
请问是什么原因？哪里出错了？感谢解答
