Didn’t have time to make it shorter. 1 solved Read file with floats, calculate size, max, min, mean, median and standard deviaton in C [closed]

[Solved] Adding standard deviation to barplot() in R

by

with base R, you can use the function arrows() : barCenters <- barplot(height = Ymeans12stdev$mean, main = “Average Time per Group”, xlab = “Group”, ylab = “Time”) arrows(barCenters, Ymeans12stdev$mean-Ymeans12stdev$sd, barCenters, Ymeans12stdev$mean+Ymeans12stdev$sd,angle=90,code=3) the argument angle=90 specifies to draw “flat” arrows (i.e. a horizontal bar on top of a vertical one) and the argument code=3 specifies to … Read more
