Re: [R] Assigning factor names to interaction plot

Hi: A small toy example: fakedata <- data.frame(group = factor(rep(1:3, each = 10), labels = paste('Therapy', 1:3)), city = factor(rep(c('Amsterdam', 'Rotterdam'), each = 5)), pressure = rnorm(30)) with(fakedata, interaction.plot(group, city, pressure, t
