Stacked Bar graph and line graph – R

Main data is stored in df, which will be the data for the bar graph, and returns

           V1      V2      V3      ...
periphery  0.659   0.626   0.720   ...
middle     0.250   0.279   0.819   ...
core       0.091   0.077   0.093   ...

then enter GINI coefficients

gco<-c(0.7,1.9,3.1 ... )

draw both bar and line graph

barplot(df,axisnames=FALSE)

we then get the x coordinates for the line graph

bgrp<-barplot(df)

and finally, we draw the line with bgrp as the x coordinates, and gco as the y coordinates

lines(bgrp,gco)
