Hi Manish,
See ?arrows, e.g.,
DF <- structure(list(names = structure(c(5L, 2L, 1L, 3L, 4L), .Label =
c("cabbage",
"potato", "sukuma-wiki", "terere", "tomato"), class = "factor"),
freq = c(7, 4, 5, 8, 20)), .Names = c("names", "freq"), row.names =
c(NA,
-5L), class = "data.frame")
barplot(as.matrix(DF[,2]), col=heat.colors(length(DF[,2])),
legend=DF[,1],xlim=c(0,9), width=2)
arrows(3.5, 15, 2.8, 20)
HTH,
Jorge.-
