Try this:
Lines <- "A B C D
8 4 9 8
7 5 4 7
6 8 4 4
3 7 6 2
5 1 8 5
6 4 7 1
2 8 3 4
1 2 4 8
4 3 1 9
"
one <- read.table(textConnection(Lines), header = TRUE)
library(zoo)
z <- zoo(as.matrix(one))
plot(z, plot.type = "single", pch = colnames(z), type = "o", col =
1:4, lty = 1:4)
legend("bottomleft", colnames(z), col = 1:4, lty = 1:4)
# or use matplot
matplot(as.matrix(one), pch = colnames(z), type = "o")
legend("bottomleft", colnames(z), col = 1:4, lty = 1:4)
