to_subdir_matrix(
  paths,
  fill.value = "",
  result_type = "matrix",
  dbg = FALSE,
  method = NA_integer_
)

Arguments

paths: vector of path strings
fill.value: value used to fill empty cells of the result matrix
result_type: one of c("matrix", "data.frame", "list"), specifying the type of object to be returned. Result type "list" is only implemented for method = 2.
dbg: if TRUE debug messages are shown
method: integer specifying the implementation method. Currently not used.

Value

matrix or data frame, depending on result_type

Examples

folder_matrix <- kwb.file::to_subdir_matrix(c("a1/b1/c1", "a1/b2", "a2"))

folder_matrix
#>      [,1] [,2] [,3]
#> [1,] "a1" "b1" "c1"
#> [2,] "a1" "b2" ""  
#> [3,] "a2" ""   ""  

dim(folder_matrix)
#> [1] 3 3

folder_matrix[folder_matrix[, 1] == "a1", ]
#>      [,1] [,2] [,3]
#> [1,] "a1" "b1" "c1"
#> [2,] "a1" "b2" ""
