By creating an object to hold your bar plot, you capture the midpoints of the bars along the abscissa that can later be used to plot the error bars. Note that dose is a numeric **column here;** in some situations it may be useful to convert it to a factor. tg <- ToothGrowth

UTSSC 10,610 views 4:38 Excel Graphs With Error Bars Tutorial By Nestor Matthews - Duration: 14:12. From there it's a simple matter of plotting our data as a barplot (geom_bar()) with error bars (geom_errorbar())! This can result in unexpected behavior and will not be allowed in a future version of ggplot2. PLAIN TEXT R: error.bar <- function(x, y, upper, lower=upper, length=0.1,...){ if(length(x) != length(y) | length(y) !=length(lower) | length(lower) != length(upper)) stop("vectors must be same length") arrows(x,y+upper, x, y-lower, angle=90, code=3, length=length,

Knowing what you actually want to show or emphasis would make things easier. Barplots using base R Let's start by viewing our dataframe: here we will be finding the mean miles per gallon by number of cylinders and number of gears.
