[R] barplot beside=TRUE - values differ on scales

Dear group,
I have been struggling to barplot two different measurements from one
subject. These two measures differ in range.  I want to plot row 1
axis on left side and row 2 values on right side.

For a given column I want to plot GN and CN next to each other.

my dput code is below

structure(c(112L, 0L, 579L, 1L, 131L, 1L, 2234L, 2L, 2892L, 1L,
528L, 0L, 582L, 2L), .Dim = c(2L, 7L), .Dimnames = list(c("GN",
"CN"), c("DC5", "DC8", "DC14", "DC18", "DC19", "DC20", "DC23"

As you can see:
   DC5 DC8 DC14 DC18 DC19 DC20 DC23
GN 112 579  131 2234 2892  528  582
CN   0   1    1    2    1    0    2

GN values are range from 100 - 3000
while CN are always -2 or -1 or 0 or 1 or 2

Also I cannot log GN values and plot because a difference in 100 units
also matters in my experiment.

Any help would be greatly appreciated.
