Plot base peak chromatograms for multiple high resolution masses in multiple samples.

plotBPC will plot for each item of a list of result-objects from getMultipleBPC the BPC traces and the spectrum at the scan where the summed intensity of all ions is max.

Usage

plotBPC(
  bpc = NULL,
  mfrow = NULL,
  skip_plots = NULL,
  ylim = NULL,
  col = NULL,
  ids = NULL,
  type = "both",
  ann = c("mdev", "mz", "none")
)

Arguments

bpc: A bpc object (list of intensity matrices, rt x mz, including several attributes as attached by getMultipleBPC).
mfrow: Specify mfrow explicitly (is optimized internally if NULL to cover n=length(bpc)).
skip_plots: Allows to block certain subplots in the mfrow matrix to better align replicates.
ylim: Can be specified specifically, will be adjusted to overall min/max otherwise.
col: Specific color vector for masses may be provided.
ids: Specific plot ids may be explicitly provided.
type: Switch between co-plot of BPC and Spectrum ("both") or BPC alone ("bpc").
ann: Select value to annotate peaks in spectrum. Usually the mass deviation from the expected value in mDa.

Value

A plot to the graphics device and NULL as invisible.

Details

plotBPC allows to get a quick overview of similar information from all samples of an experimental set. As it uses `mfrow` to arrange samples its output can not be used as subplot in other figures.

Examples

# load example raw data
bpc <- HiResTEC::res_list[[1]][["bpc"]][c(1:2, 13:14)]
plotBPC(bpc = bpc)

plotBPC(bpc = bpc, ann="mz", ids=LETTERS[1:4], mfrow=c(3,2), skip_plots=c(2,3))
