formatr中的usage函数意外删除白色。请参阅以下示例：

library(formatR)
library(tidyverse)
usage(
    FUN           = inner_join
  , width         = getOption("width")
  , tidy          = c(TRUE, FALSE)[1]
  , output        = c(TRUE, FALSE)[1]
  , indent.by.FUN = c(TRUE, FALSE)[2]
  , fail          = c("warn", "stop", "none")
)

inner_join(x, y, by = NULL, copy = FALSE, suffix = c(".x", ".y"), ..., keep = FALSE)

但是，我想要这样的东西：

inner_join(
  x,
  y,
  by = NULL,
  copy = FALSE,
  suffix = c(".x", ".y"),
  ...,
  keep = FALSE
)
