)

`graphic_obj`	A ggplot() graphics handle. Initialize with g <- ggplot() to create an empty ggplot handle
`mod`	A character vector for specific peptide/modified peptide to extract I.e. 'ANSSPTTNIDHLK'/'ANS(UniMod:21)SPTTNIDHLK(UniMod:259)'. The MODIFIED_SEQUENCE column is used
`df_lib`	A data.table containing spectral library information
`chromatogram_file`	A character vector of the absolute path and filename of the chromatogram file. (Must be .mzML or sqMass format)
`chromatogram_data_points_list`	(Optional) Pass a list containing chromatogram data.
`in_osw`	A character vector of the absolute path and filename of the OpenSwath Output file. (Must be .osw) @TODO maybe make this more robust for tsv files as well?
`df_osw`	An optional dataframe containing OpenSwath Results information. (Use this if you have a dataframe cached in memory)
`SCORE_IPF`	Do you want to extract IPF Score if present? (Default: FALSE. will use MS2 m-scores)
`annotate_best_pkgrp`	Annotate the ebst peak group
`transition_type`	A vector containing possible choices for dispalying one of the following transition group types. getXIC needs to be called for each option (Options: c('precursor', 'detecting', 'identifying') )
`max_Int`	A numeric value indicating the maximum intensity. This is used for FacetZooming the y-axis. (Default: NULL)
`smooth_chromatogram`	A list object containing the polynomial filter order (p), and the bandwidth (number of data-points to smooth over, n). (Default: list(p=4, n=9))
`doFacetZoom`	A logical value for calling Facet_Zoom function to zoom in the y axis based on the max_Int/4. (Default: FALSE)
`FacetFcnCall`	A personalized function call to Facet_Zoom. I.e. FacetFcnCall = facet_zoom(xlim = c(3950, 4050), ylim = c(0, 10000)). (Default: NULL)
`top_trans_mod_list`	A list containing a data.table/data.frame of the current peptide(mod peptide) with information for transition ids and top posterior error probabilities.
`transition_selection_list`	A list containing transitions to display for unique identifying. i.e. transition_selection_list <- list( y = c(3), b = c(8:10) )
`RT_pkgrps`	A numeric vector of the alternative peak group ranks to display. I.e. c(2, 4) (Default: NULL)
`show_manual_annotation`	a dataframe with leftWidth and rightWidth retention time boundary values of a manually annotated peak. Will draw a transparent blue shaded rectangle indicating manual annotation. I.e data.frame(leftWidth=300, rightWidth=330)
`show_peak_info_tbl`	A logical value. Show peak information table containing RT, rank, ms2-mscore, ipf_pep, ipf-mscore. (Default: FALSE)
`plotIdentifying.Unique`	A logical value. TRUE will plot unique identifying transitions. (Default: NULL)
`plotIdentifying.Shared`	A logical value. TRUE will plot shared identifying transitions. (Default: NULL)
`plotIdentifying.Against`	A logical value. TRUE will plot against identifying transitions. (Default: NULL)
`show_n_transitions`	A numeric value indicating the number of transitions to draw. (Default: NULL, default is 6 transitions)
`transition_dt`	A data.table containing TRANSITION_SCORE Information obtained from the OSW file using getTransitionScores_. (Default: NULL)
`show_legend`	A logical value. Display legend information for transition id, m/z and charge. (Default: TRUE)
`mzPntrs`	A list object containing cached mzR objects.
`unit_mod_list`	A list of potential modifiable forms. (Default: NULL)
`df`	A data.frame/data.table/matrix object to check for number of rows
`return_item`
`msg`	error message to return
`numeric_obj`	Check if an numeric object is not NULL
`signif.not`	Return significant notation
