R 从具有多个统计测试结果列表的列表中提取statiscal值

我在r中做了一个Ljung-Box独立性测试，有36个滞后，并将结果存储在一个列表中

for (lag in c(1:36)){
box.test.list[[lag]] <- (Box.test(btcr, type = "Ljung", lag))
}

for（滞后于c（1:36））{
box.test.list[[lag]]和测试数据

set.seed(7)
btcr <- rnorm(100)

box.test.list <- lapply(1:36, function(i) Box.test(btcr, type = "Ljung", i))

results <- data.frame(
  lag = 1:36, 
  xsquared = sapply(box.test.list, "[[", "statistic"), 
  pvalue = sapply(box.test.list, "[[", "p.value")
)

head(results)
#   lag  xsquared     pvalue
# 1   1  3.659102 0.05576369
# 2   2  7.868083 0.01956444
