使用 purrr::map 重命名更大列表中列表中元素的行名称?
using purrr::map to rename row names in elements within lists in a bigger list?
{library(Seurat)
library(tidyverse)
library(purrr)}
dirNames <- unique(dirname(list.files("data/scRNA_CITE",
full.names = T,
recursive = T)))
######
#reading multiple directories and a resultant list
dat <- purrr::map(dirNames, Read10X)
names(dat) <- dirNames
#reading just one file
#M06 <- Read10X(data.dir = "data/m06/filtered_feature_bc_matrix/")
#renaming the rows of a list element (here named antibody capture) within one list works!
rownames(x = M06[["Antibody Capture"]]) <- gsub(pattern = "*_TotalSeqC", replacement = "",
x = rownames(x = M06[["Antibody Capture"]]))
#creating function for purrr
change_rname <- function(x){
rownames(x[["Antibody Capture"]]) <- sub(pattern = "*_TotalSeqC", replacement = "", x[["Antibody Capture"]])
}
# using the same function to rename multiple elements within multiple lists of a bigger list works temporarily BUT DOES not get saved within the bigger list
purrr::map(dat,
~change_rname(.x))
我不确定如何为此制作一个 reprex,以允许加载文件。如何使该函数与 purrr 一起工作并允许在列表元素内重命名?
