ggplot each group consists of only one observation

Question

I\'m trying to make a plot similar to this answer: https://stackoverflow.com/a/4877936/651779

My data frame looks like this:

df2 <- read.table(tex         


        

Answer 1

Add group = samples to the aes of geom_line. This is necessary since you want one line per samples rather than for each data point.

ggplot(df2, aes(measurements, value)) + 
  geom_line(aes(colour = samples, group = samples))
