QC_plots_features(FeatureMatrix, classVector, COI = NULL,
  NA_numeric_limit = NULL, plottitle = NULL, BOI_vector = NULL,
  BOI = NULL, RDSplot_text_adjustheigt = 0)

`FeatureMatrix`	the matrix of Features (obtained by using the xcms::groupval function). Matrix has to have columns for features and rows for samples.
`classVector`	The vector of sample classes.
`COI`	(optional) In case only a specific class is of interest.
`NA_numeric_limit`	If missing values are not indicated as NA but with a numeric value like 0, supply the numerical value under which values are considered missing.
`plottitle`	(optional) Plot title
`BOI_vector`	(optional) In case the RSD's need only be calculated for a specific subset of batches, provide the character/factor vector witch batches here (same length as the number of rows in FeatureMatrix).
`BOI`	(optional) The name of the batch of interest. BOI_vector has to be supplied as well
`RDSplot_text_adjustheigt`	Height adjustment for the count number in the RSD boxplot visuzlization.
