您好：在做逻辑回归的列线图时，最后一步提示出现一下错误：
Error in lims[[i]] : subscript out of bounds
In addition: Warning message:
In structure(limits, class = "data.frame", row.names = c("Low:effect",  :
  Calling 'structure(NULL, *)' is deprecated, as NULL cannot have attributes.
  Consider 'structure(list(), *)' instead.
翻看之前帖子说是数据下标出界，我想问一下这种情况具体要怎么调整？
