fread2

Read text file(s)

Read text file(s)

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

`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.

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

tmp <- fwrite2(iris)
iris2 <- fread2(tmp)
all.equal(iris2, iris)  ## fread doesn't use factors
