#' Join a table with \code{microorganisms}
|
|
#'
|
|
#' Join the dataset \code{\link{microorganisms}} easily to an existing table or character vector.
|
|
#' @rdname join
|
|
#' @name join
|
|
#' @aliases join inner_join
|
|
#' @param x existing table to join, also supports character vectors
|
|
#' @param by a variable to join by - could be a column name of \code{x} with values that exist in \code{microorganisms$bactid} (like \code{by = "bacteria_id"}), or another column in \code{\link{microorganisms}} (but then it should be named, like \code{by = c("my_genus_species" = "fullname")})
|
|
#' @param suffix if there are non-joined duplicate variables in \code{x} and \code{y}, these suffixes will be added to the output to disambiguate them. Should be a character vector of length 2.
|
|
#' @param ... other parameters to pass on to \code{dplyr::\link[dplyr]{join}}.
|
|
#' @details As opposed to the \code{\link[dplyr]{join}} functions of \code{dplyr}, characters vectors are supported and at default existing columns will get a suffix \code{"2"} and the newly joined columns will not get a suffix. See \code{\link[dplyr]{join}} for more information.
