Question

我有多个 .rds 文件，需要将它们合并为一个 .rds 文件。

[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"

我能够将它们整合到一个列表中：

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

.rds 文件是 data.frame 文件。我应该如何将它们组合成一个大的 .rds 文件？

先谢谢你！

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)

将多个 .rds 文件合并为一个
