plotMvsAPairs.matrix {aroma.light} | R Documentation |
Plot log-ratios/log-intensities for all unique pairs of data vectors.
## S3 method for class 'matrix': plotMvsAPairs(X, Alab="A", Mlab="M", Alim=c(0, 16), Mlim=c(-1, 1) * diff(Alim), pch=".", ..., add=FALSE)
X |
NxK matrix where N is the number of observations and
K is the number of channels. |
Alab,Mlab |
Labels on the x and y axes. |
Alim,Mlim |
Plot range on the A and M axes. |
pch |
Plot symbol used. |
... |
Additional arguments accepted by points . |
add |
If TRUE , data points are plotted in the current plot,
otherwise a new plot is created. |
Log-ratios and log-intensities are calculated for each neighboring pair of channels (columns) and plotted. Thus, in total there will be K-1 data set plotted.
The colors used for the plotted pairs are 1, 2, and so on. To change the colors, use a different color palette.
Returns nothing.
