Hi,
I didn't see a response for this so here is one way to approach it using the
reshape2 and ggplo2 packages.
library(reshape2)
library(ggplot2)
dat1<-read.table(text="
year strong medium healtly
2007 0.606000 0.5101442 0.6226696
2006 1.398500 1.2362115 1.5150000
2005 2.242083 1.9661923 2.4346957
2004 2.981229 2.6141827 3.2402000
2003 3.403312 3.1088077 3.7789478
2002 4.101750 3.8283269 4.5865130
2001 4.991583 4.8069038 5.6671391
",sep="",header=TRUE,stringsAsFactors=FALSE)
str(dat1)
dat2 <- melt(dat1, id=c("year"))
p <- ggplot(dat2, aes(year, value, colour = variable )) + geom_line()
p
