#' Retrieve a single analysis result set by its identifier

#'
#' @param resultSet An expression analysis result set numerical identifier.
#' @param raw \code{TRUE} to receive results as-is from Gemma, or \code{FALSE} to enable
#' parsing. Raw results usually contain additional fields and flags that are
#' omitted in the parsed results.
#' @param memoised Whether or not to save to cache for future calls with the
#' same inputs and use the result saved in cache if a result is already saved.
#' Doing \code{options(gemma.memoised = TRUE)} will ensure that the cache is always
#' used. Use \code{\link{forget_gemma_memoised}} to clear the cache.
#' @param file The name of a file to save the results to, or \code{NULL} to not write
#' results to a file. If \code{raw == TRUE}, the output will be the raw endpoint from the

#' Retrieve all result sets matching the provided criteria
#'
#' Returns queried result set
#'
#' @details Output and usage of this function is mostly identical to \code{\link{get_dataset_differential_expression_analyses}}.
#' The principal difference being the ability to restrict your result sets, being able to
#' query across multiple datasets and being able to use the filter argument
#' to search based on result set properties.
#'
#' @param datasets A vector of dataset IDs or short names
#' @param resultSets A resultSet identifier. Note that result set identifiers
#' are not static and can change when Gemma re-runs analyses internally. Whem
#' using these as inputs, try to make sure you access a currently existing
#' result set ID by basing them on result sets returned for a particular dataset or
#' filter used in \code{\link{get_result_sets}}
#' @param filter Filter results by matching expression. Use \code{\link{filter_properties}}
#' function to get a list of all available parameters. These properties can be
#' combined using "and" "or" clauses and may contain common operators such as "=", "<" or "in".
#' (e.g. "taxon.commonName = human", "taxon.commonName in (human,mouse), "id < 1000")
#' @param offset The offset of the first retrieved result.
#' @param limit Defaults to 20. Limits the result to specified amount
#' of objects. Has a maximum value of 100. Use together with \code{offset} and
#' the \code{totalElements} \link[base:attributes]{attribute} in the output to
#' compile all data if needed.
#' @param sort Order results by the given property and direction. The '+' sign
#' indicate ascending order whereas the '-' indicate descending.
#' @param raw \code{TRUE} to receive results as-is from Gemma, or \code{FALSE} to enable
#' parsing. Raw results usually contain additional fields and flags that are
#' omitted in the parsed results.
#' @param memoised Whether or not to save to cache for future calls with the
#' same inputs and use the result saved in cache if a result is already saved.
#' Doing \code{options(gemma.memoised = TRUE)} will ensure that the cache is always
#' used. Use \code{\link{forget_gemma_memoised}} to clear the cache.
#' @param file The name of a file to save the results to, or \code{NULL} to not write
#' results to a file. If \code{raw == TRUE}, the output will be the raw endpoint from the
#' API, likely a JSON or a gzip file. Otherwise, it will be a RDS file.

#' Retrieve all platforms matching a set of platform identifiers
#'
#'
#'
#' @param platforms Platform numerical identifiers or platform short names.  If not

#' @param filter Filter results by matching expression. Use \code{\link{filter_properties}}
#' function to get a list of all available parameters. These properties can be
#' combined using "and" "or" clauses and may contain common operators such as "=", "<" or "in".
#' (e.g. "taxon.commonName = human", "taxon.commonName in (human,mouse), "id < 1000")
#' @param taxa A vector of taxon common names (e.g. human, mouse, rat). Providing multiple
#' species will return results for all species. These are appended
#' to the filter and equivalent to filtering for \code{taxon.commonName} property
#' @param offset The offset of the first retrieved result.
#' @param limit Defaults to 20. Limits the result to specified amount
#' of objects. Has a maximum value of 100. Use together with \code{offset} and
#' the \code{totalElements} \link[base:attributes]{attribute} in the output to
#' compile all data if needed.
#' @param sort Order results by the given property and direction. The '+' sign
#' indicate ascending order whereas the '-' indicate descending.
#' @param raw \code{TRUE} to receive results as-is from Gemma, or \code{FALSE} to enable
#' parsing. Raw results usually contain additional fields and flags that are
#' omitted in the parsed results.
#' @param memoised Whether or not to save to cache for future calls with the
#' same inputs and use the result saved in cache if a result is already saved.
#' Doing \code{options(gemma.memoised = TRUE)} will ensure that the cache is always
#' used. Use \code{\link{forget_gemma_memoised}} to clear the cache.
#' @param file The name of a file to save the results to, or \code{NULL} to not write
#' results to a file. If \code{raw == TRUE}, the output will be the raw endpoint from the
#' API, likely a JSON or a gzip file. Otherwise, it will be a RDS file.
#' @param overwrite Whether or not to overwrite if a file exists at the specified
#' filename.
