# S3 method for repl
merge(
  dt.x,
  dt.y,
  sep = "_",
  replace_NA = TRUE,
  force_y = TRUE,

# S3 method for repl
merge(
  dt.x,
  dt.y,
  sep = "_",
  replace_NA = TRUE,
  force_y = TRUE,
  overwrite_x = FALSE,
  keep_order = FALSE,
  keep_colorder = TRUE,
  keep_factor = TRUE,
  ...
)

Arguments

replace_NA: logical, only use values in dt.y, any dt.x not in dt.y is clobbered (NA)
force_y: logical, should x and y common columns be merged?
overwrite_x: logical, if force_y = TRUE, should NA values in y replace x?

Value

A data.table
