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, We can then rename the columns just for ease of use. We have our x values given by bp[,1] and the y values given by the vector c(m.v1, m.v2, m.v3), which is the height vector we used above for plotting. http://waspsoft.com/error-bar/bar-plots-in-r-with-error-bars.html

With stat="bin", it will attempt to set the y value to the count of cases in each group. If you want y to represent values in the data, use stat="identity". 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. r ggplot2 bar-chart share|improve this question asked Apr 21 '15 at 9:32 tlorin 173213 1 beware by doing t(plot) you completely inversed the gene ;) –Colonel Beauvel Apr 21 '15
