Not sure whether it is a scatterplot or just a plot with 3 lines. If it is the
latter,
library(reshape2)
matplot(acast(my.df, TIME~ID, value.var='X'), type='l', col=1:3,
ylab='X', xlab='TIME')
legend('bottomright', inset=.05, legend=LETTERS[1:3], pch=1, col=1:3)

Hi Arun,
I hope you are doing well.
I have a data set as follow:
my.df <- data.frame(ID=rep(c("A","B","C"), 5),
TIME=rep(1:5, each=3), X=1:5)
I would like to get a scatterplot where x axis is Time (1,2,3,4,5) and y axis is
X, but I want to have three lines separately for each ID.
I basically want to tack each ID over time. Is this possible?
Thanks a lot and Happy Holidays to you!
It seems that you would like to make a spaghetti plot (in a longitudinal data analysis). You can use the function 'interaction.plot()'. > with(my.df, interaction.plot(TIME, ID, X)) I hope this helps.
