plotMsData {xcms} | R Documentation |
UPDATE: please use plot(x, type = "XIC")
from the MSnbase
package
instead. See examples below.
The plotMsData
creates a plot that combines an (base peak )
extracted ion chromatogram on top (rt against intensity) and a plot of
rt against m/z values at the bottom.
plotMsData(x, main = "", cex = 1, mfrow = c(2, 1), grid.color = "lightgrey", colramp = colorRampPalette(rev(brewer.pal(9, "YlGnBu"))))

grid.color |
a color definition for the grid line (or |
colramp |
a color ramp palette to be used to color the data points
based on their intensity. See argument |
