Hi Xin,
Fortunately, this wheel is pretty easy to reinvent:

require(plotrix)
x1<-rnorm(7)
x2<-rnorm(27)
x3<-rnorm(47)
x4<-rnorm(67)
allxlim<-c(1,67)
allylim<-range(c(x1,x2,x3,x4))
panes(matrix(1:4,nrow=2,byrow=TRUE),widths=c(1.1,1),
  heights=c(1,1.1))
par(mar=c(0,4,2,0))
plot(sort(x1),xlim=allxlim,ylim=allylim,type="s",
  main="",ylab="",xlab="",xaxt="n")
tab.title("Plot of x1",tab.col="orange")
par(mar=c(0,0,2,1))
plot(sort(x2),xlim=allxlim,ylim=allylim,type="s",
  main="",ylab="",xlab="",xaxt="n",yaxt="n")
tab.title("Plot of x2",tab.col="orange")
par(mar=c(4,4,2,0))
plot(sort(x3),xlim=allxlim,ylim=allylim,type="s",
  main="",ylab="",xlab="")
tab.title("Plot of x3",tab.col="orange")
par(mar=c(4,0,2,1))
plot(sort(x4),xlim=allxlim,ylim=allylim,type="s",
  main="",ylab="",xlab="",yaxt="n")
tab.title("Plot of x4",tab.col="orange")
