estimate_measurementdata_download_size: Estimate downloaded size for measurement data

In Paradigm4/insight: SciDB REVEAL/Genomics API

Description

(1.) This currently estimates data per pipeline (cannot estimate a subset by feature i.e. genes or biosamples) (2.) The estimate is a rough estimate e.g. RNA-seq data will have estimate for multiple columns that are eventually not present in the expression matrix (e.g. dataset_id, dataset_version, biosample_id, feature_id, measurementset_id). Some of these columns are important to link metadata to the measurement data, and only those are eventually downloaded from the database. (3.) For now this is only used to estimate the data size in the measurement array (not the feature and any other metadata that might also be downloaded to form a compound object e.g. search_expression returns a Bioconductor ExpressionSet object).

Usage

estimate_measurementdata_download_size(
  measurementset,
  units = c("MB", "KB", "GB"),
  con = NULL
)

Arguments

measurementset	measurementset dataframe – e.g. output of get_measurementset() or search_measurementset(dataset_id = ...)
units	return estimated size as either of "KB", "MB" (default) or "GB"
con	the connection object (optional)
