Hi,

Using legend as an argument within the call to barplot will automatically
add the color key to the legend. I don't know how to add the colors using
legend separately. Try this revised code:

y <-
matrix(c(46.5102,42.7561,45.7857,45.6047,45.7027,81.4565,69.8824,69.1333,67.56,57.8929,43.3019,42.9184,
                     
51.7143,40.2727,51.7692,22.3871,24.2222,24.3226,23.6342,21.5833), ncol=4)

se <-
matrix(c(13.0707,12.0287,15.3949,16.5344,10.2520,28.6169,31.2398,24.5816,25.9745,22.9981,13.8433,17.3071,
                        
21.7355,18.2007,26.2546,6.8199,7.2977,7.1245,7.2345,8.2616), ncol=4)

plot <- barplot(
  y, 
  beside = TRUE, 
  ylim = c(0, 90), 
  axis.lty = 0.5,
  xlab = "Light treatment", 
  ylab = "root length (mm)", 
  main = "Root", 
  names.arg = c("White","Blue","Red","Far-red"),
  legend = c("Sedingehult", "Mobranna", "Aunasvare", "Fallan", "Ylinen")
)

segments(plot, y - se, plot, y + se)
