plotMvsA.matrix {aroma.light} | R Documentation |
Plot log-ratios vs log-intensities.
## S3 method for class 'matrix': plotMvsA(X, Alab="A", Mlab="M", Alim=c(0, 16), Mlim=c(-1, 1) * diff(Alim), pch=".", ..., add=FALSE)
X |
Nx2 matrix with two channels and N observations. |
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 |

otherwise a new plot is created. |
