[R] bar plot add space to group data

[Jim Lemon]

Hi citc,
Try this:

geac<-matrix(c(9,9,8,8,8,23,23,23,23,22,27,27,27,25,24,
 19,19,19,20,20,17,17,17,18,19,8,8,8,9,9,2,2,3,3,3),ncol=5,byrow=TRUE)
library(plotrix)
barp(geac,names.arg=2014:2018,main="A level grades chemistry",
 xlab="Year",ylab="Percentage of each grade",ylim=c(0,30),
 col=c("white","lightblue","blue","orange","green","red","pink"))
