Arguments

obj

An analysisInfo data.frame object as obtained by generateAnalysisInfo function.

retentionRange

Range of retention time (in seconds), m/z, respectively. Should be a numeric vector with length of two containing the min/max values. The maximum can be Inf to specify no maximum range. Set to NULL to skip this step.

MSLevel

Integer vector with the ms levels (i.e., 1 for MS1 and 2 for MS2) to obtain traces.

retMin

Plot retention time in minutes (instead of seconds).

title

Character string used for title of the plot. If NULL a title will be automatically generated.

colourBy

Sets the automatic colour selection: "none" for a single colour or "analyses"/"rGroups" for a distinct colour per analysis or analysis replicate group.

showLegend

Plot a legend if TRUE.

xlim, ylim

Sets the plot size limits used by plot. Set to NULL for automatic plot sizing.

...

Further arguments passed to plot.

Functions

• getTICs(data.frame): Obtain the total ion chromatogram/s (TICs) of the analyses.

• getBPCs(data.frame): Obtain the base peak chromatogram/s (BPCs) of the analyses.

• plotTICs(data.frame): Plots the TICs of the analyses.

• plotBPCs(data.frame): Plots the BPCs of the analyses.
