r-将多个.rds文件合并为一个

Question

我有多个.rds文件，需要将它们合并为一个.rds。

[1] "RDS_Species/SeaTurtles/Caretta_caretta_IUCN.rds"       
[2] "RDS_Species/SeaTurtles/Chelonia_mydas_IUCN.rds"        
[3] "RDS_Species/SeaTurtles/Dermochelys_coriacea_IUCN.rds"  
[4] "RDS_Species/SeaTurtles/Eretmochelys_imbricata_IUCN.rds"
[5] "RDS_Species/SeaTurtles/Lepidochelys_olivacea_IUCN.rds"

我能够将它们列为一个列表：

SeaTurtles_IUCNdist <- list.files(path="RDS_Species/SeaTurtles/",
pattern = ".rds$", full.names = TRUE) %>%
map(readRDS) 

.rds文件是data.frame文件。我应该如何将它们合并为一个大型.rds文件？

提前谢谢！

Answer 1

我们可以使用map_dfr

library(dplyr)
library(purrr)
SeaTurtles_IUCNdist <- list.files(path="RDS_Species/SeaTurtles/",
pattern = ".rds$", full.names = TRUE) %>%
map_dfr(readRDS)
