我有一个带有以下表格的列表:
x = replicate(3, list(m = matrix(rnorm(16), 4, 4), s = rnorm(1)), simplify=FALSE)
x
#[[1]]
#[[1]]$m
# [,1] [,2] [,3] [,4]
#[1,] -0.412209 -0.50227 -2.62340 0.17549
#[2,] 1.344723 -1.52060 -0.59093 1.19701
#[3,] -0.016289 -0.88286 -0.33307 -0.48351
#[4,] 0.060760 0.32131 1.16896 -0.45940
#
#[[1]]$s
#[1] -1.3588
#
#
#[[2]]
#[[2]]$m
# [,1] [,2] [,3] [,4]
#[1,] -0.15345 -0.82106 0.93839 1.46115
#[2,] 1.60950 -2.35833 0.89621 0.35542
#[3,] -0.17792 0.54444 -0.17414 0.63614
#[4,] 0.85038 0.84373 0.24687 0.60172
#
#[[2]]$s
#[1] 3.6597
#
#
#[[3]]
#[[3]]$m
# [,1] [,2] [,3] [,4]
#[1,] 1.27724 0.19397 0.47393 -0.66518
#[2,] -0.75244 1.16476 1.74843 -1.03732

目标是从上面的列表中获取矩阵列表,以及标量向量。如何才能做到这一点?谢谢!
