[R] 'matplot' for matrix with NAs: broken lines

I know that points involving NAs are not plotted in 'matplot', but when I plot them as lines, I still want the lines to connect all the points (i.e. not broken where there are NAs). Please see the example below. How can I achieve this in 'matplot'? If I can't, any good alternatives so I don't have to use 'plot' + 'lines' and loop through all the columns.
> a=b=matrix(rnorm(9), 3,3)
> matplot(a, type="b")
> matplot(b, type="b") ## I want the two "2" connected!
> matplot(b, type="l") ## Now my data for the second column are missing from the graph
