Dear researchers
I wish to plot a box plot without the mean line (the black line) and plot
only the mean (red square). Futhermore, is it possible to add standard
error and/or stadard deviation?
This is an example
mytest <- c(2.1,2.6,2.7,3.2,4.1,4.3,5.2,5.1,4.8,1.8,1.4,2.5,2.7,3.1,2.6,2.8)
boxplot(mytest,lty = "solid")
means <- mean(mytest,na.rm=TRUE)
points(means, pch = 22, col = "red")
thanks in advance
Gianni
