factanal()

2# ltx5151
factanal(x = applican.dat1, factors = 2, scores = "regression",
rotation = "varimax", method = "principal",cor=F)与factanal(x = applican.dat1, factors = 2, scores = "regression",
rotation = "varimax", method = "principal"，cor＝T)为什么估计出来是一样的？

因为factanal参数中没有cor这一项：
factanal(x, factors, data = NULL, covmat = NULL, n.obs = NA,
         subset, na.action, start = NULL,
         scores = c("none", "regression", "Bartlett"),
         rotation = "varimax", control = NULL, ...)

所以cor=T，Cor=F对结果没有任何影响
