在做空间面板固定效应回归时遇到这样的问题：

regress<-spml(formula = fm, data = test1, index = NULL,listw = tmm1, lag = TRUE,model = "within",effect = "individual", method = "eigen", na.action = na.pass,...)
Error in subset.listw(listw, subset, zero.policy = zero.policy) :
  Not yet able to subset general weights lists


小人百思不得其解错误出在哪里，请大神们指教。是权重矩阵的设置有问题吗？general weights lists是什么意思?

令求问有没有专业的空间计量R语言参考书，谢谢！如有满意答案，奉上微薄论坛币
