msms_search: Encapsulation of CEU Mass Mediator batch search API.

Description

batch_search returns the dataframe of all the database search results. using the following code to install the dependencies: install.packages(c("httr", "progress", "RJSONIO"))

Usage

msms_search(ion_mass, ms_ms_peaks, precursor_ion_tolerance = 100,
  precursor_ion_tolerance_mode = "mDa", precursor_mz_tolerance = 500,
  precursor_mz_tolerance_mode = "mDa", ion_mode,
  ionizationVoltage = "all", spectra_types = "experimental",
  cmm_url = "http://ceumass.eps.uspceu.es/mediator/api/msmssearch")

Value

If all inputs are all correctly formatted, a dataframe will be returned for the result.
