R help - Mar 2022 - inserting relative path - purrr

R-help

Having to perform an iteration so I'm looking at the purr package.  The
problem I had was the files (*.csv) are in a Data subdirectory so I used the
paste0 function to concatenate the subdirectory's relative path and the file
name from the files list. While this works just fine is there a better way
of adding the files path?

# Load purrr library
library(purrr)

# Use map to iterate
all_files_purrr <- map(paste0("../Data/", files), read_csv)

# Output size of list object
length(all_files_purrr)

?file.path
