如何快速结合R中的60个矩阵 [英] how to combine 60 matrices in R quickly

问题描述

我在R中有60个矩阵，分别命名为mat1，mat2 .... mat60，我想使用rbind将它们组合成一个大矩阵.我知道我可以写类似的东西

matList <- list(mat1, mat2, ... mat60)
rbind(matList)

但是这似乎是一个非常愚蠢的解决方案.知道如何简化流程吗?

我认为这个问题真的与OP必须手动键入矩阵名称有关.您可以使用mget返回列表中的矩阵，然后使用@Michele构成的do.call和rbind这样(假设矩阵位于.GlobalEnv中):

matList <- mget(paste0("mat",1:60),env=globalenv())
bigm <- do.call("rbind" , matList)

I have 60 matrices in R named as mat1, mat2....mat60 and I would like to combine them into a big matrix using rbind. I know that I could write something like

matList <- list(mat1, mat2, ... mat60)
rbind(matList)

but it seems a very dumb solution. Any idea how I can simplify the process?

解决方案

I think this question really relates to the OP having to type out the names of the matrices manually. You can use mget to return the matrices in a list and then use do.call and rbind as posed by @Michele like this (assuming the matrices are located in the .GlobalEnv ):

matList <- mget(paste0("mat",1:60),env=globalenv())
bigm <- do.call("rbind" , matList)
