Hi Eliza,
Try this:

BAS1<-
structure(c(3, 4, 2, 3, 3, 4, 3, 3, 3, 3, 2, 3, 3, 4, 3, 2, 2,
3, 2, 3, 3, 3, 4, 5, 3, 4, 3, 4, 4, 3, 4, 4, 3, 3, 3, 4, 3, 3,
3, 4, 3, 3, 4, 5, 4, 4, 4, 3, 4, 3, 3, 3, 3, 4, 4, 5, 4, 3, 4,
4, 2, 3, 3, 3, 2, 4, 4, 3, 3, 4, 3, 3, 3, 3, 4, 4, 3, 3, 2, 3,
3, 3, 3, 2, 5, 2, 4, 3, 2, 3, 4, 3, 4, 4, 3, 4, 4, 3, 3, 3, 2,
3, 4, 3, 4, 4, 3, 3, 3, 3, 5, 3, 3, 5, 3, 4, 2, 3, 3, 3, 3, 3,
4, 3, 3.93, 3.509, 2.464, 2.72, 2.304, 3.517, 3.517, 6.675, 6.597,
2.715, 2.849, 2.618, 3.126, 2.715, 3.931, 3.709, 3.931, 4.145,
6.585, 3.907, 3.132, 2.568, 3.883, 2.447, 3.517, 7.098, 3.027,
3.003, 7.098, 2.374, 2.065, 2.95, 3.559, 5.102, 3.907, 3.204,
3.207, 2.791, 2.116, 3.003, 3.003, 3.003, 6.049, 3.52, 2.241,
3.883, 4.145, 3.334, 3.151, 6.269, 4.04, 3.883, 2.27, 3.304,
2.464, 4.111, 2.728, 3.93, 3.911, 2.447, 3.202, 2.375, 2.442,
2.442, 2.592, 2.13, 3.122, 5.657, 6.076, 4.186, 2.115, 2.623,
6.076, 2.467, 2.623, 2.629, 2.517, 2.623, 2.517, 4.32, 4.045,
6.597, 4.079, 3.817, 3.521, 2.564, 3.071, 2.447, 3.334, 2.442,
2.248, 3.094, 4.045, 4.045, 2.252, 2.971, 3.727, 2.184, 2.783,
2.849, 3.529, 2.484, 2.184, 2.313, 2.512, 3.4, 4.096, 3.572,
2.663, 3.405, 5.102, 3.267, 2.987, 2.123, 3.47, 2.512, 2.783,
6.597, 6.435, 4.921, 3.351, 2.07, 2.07, 2.442), .Dim = c(124L,
2L))
library(plotrix)
x11(width=12,height=5)
barp(BAS1[,1],main="Plot of BAS1",ylim=c(0,10),col="green")
plotlim<-par("usr")
rect(seq(0.6,123.6,1),plotlim[4]-BAS1[,2],
 seq(1.4,124.4,1),plotlim[4],col="red")

This clearly needs refinement, but it's a start.

> I want to draw bar chart in such a way that column 1 is drawn on primary y axis with bars rising, while the column 2 is draw on a secondary y axis with bar-plots falling down from the top exactly on the top of rising bars. For example, the plot of 1st row of column one should be overshadowed by the bar of 1st row of column 2. Additionally, I want all the bars to be red while 3rd and 102nd bar of rising and falling bars to be coloured green.
