R “拉什收敛”；“算法不收敛”&引用；拟合概率数值为0或1；

我有一个问题，我在R中使用函数“rasch”包“ltm”来获得困难的估计值，但当我将其用于

x <- data.frame(matrix(data = c(0,1,1,0,1,0,1,0,1,1,1,1,1,1,1,1,0,0,1,0,1,0,1,0,1,0,
                       1,1,1,1,0,1,0,0,1,0,1,0,0,0,0,0,1,1,1,0,0,1,0,0,1,0,
                       1,0,1,0,1,0,1,1,1,0,0,1,0,0,1,0,0,0,0,0,0,0,0,1,1,0,
                       0,1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0),ncol = 6, nrow = 16))

rasch(x)

我怎样才能解决这个问题

请帮忙
