Read text file(s) — fread2 • bigreadr

Read text file(s)

fread2(input, ..., data.table = FALSE,
  nThread = getOption("bigreadr.nThread"))

Arguments

input: Path to the file(s) that you want to read from. This can also be a command, some text or an URL. If a vector of inputs is provided, resulting data frames are appended.
...: Other arguments to be passed to data.table::fread.
data.table: Whether to return a data.table or just a data.frame? Default is FALSE (and is the opposite of data.table::fread).
nThread: Number of threads to use. Default uses all threads minus one.

Value

A data.frame by default; a data.table when data.table = TRUE.

Examples

tmp <- fwrite2(iris)
iris2 <- fread2(tmp)
all.equal(iris2, iris)  ## fread doesn't use factors
#> [1] "Component \"Species\": Modes: character, numeric"                      
#> [2] "Component \"Species\": Attributes: < target is NULL, current is list >"
#> [3] "Component \"Species\": target is character, current is factor"
