You have forgotten drop=FALSE in mat[1,]: take a look at what it produces. See ?Extract for more details.

Would a specialist of the "point" or "plot" functions try the following:
mat<-matrix(c(1.836767,4.025989,0.6396777,0.3764444),ncol=2) plot(mat) points(mat[1,],col="red")
..A lag appears on x for mat [1,1] between the two displays.
I wonder if this example may be due to a bug or to the mis-use of a matrix in the plot() points() functions. In case of mise-use which kind can it be?
Not using a matrix at all!
