One way that we can construct these grap

I just encountered this issue revising a paper for submission and figured I'd share my code. The following simple function will plot reasonable error bars on a bar plot. PLAIN TEXT R: error.bar <- function(x, y, http://monkeysuncle.stanford.edu/?p=485 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, ...) } Now let's use it. First, I'll create 5 means drawn from a Gaussian random variable with unit mean and variance. I want to point out another mild annoyance with the way that R handles bar plots, and how to fix it. By default, barplot() suppresses the X-axis. Not sure why. If you want the axis to show up with the same line style as the Y-axis, include the argument axis.lty=1, as below. 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. PLAIN TEXT R: y <- rnorm(500, mean=1) y <- matrix(y,100,5) y.means <- apply(y,2,mean) y.sd <- apply(y,2,sd) barx <- barplot(y.means, names.arg=1:5,ylim=c(0,1.5), col="blue", axis.lty=1, xlab="Replicates", ylab="Value (arbitrary units)") error.bar(barx,y.means, 1.96*y.sd/10) Now let's say

dataset, and are easy to graph with Plotly and R! Error bars can be used to visualize standard deviations, standard errors or confidence intervals (just don't forget to specify which measure the error bar in the graph represents). Below are two examples that demonstrate how to graph a variety of error bars. The complete R script and data used to create these 2 graphs are available here! To create vertical error bars, like on the Snow line in the graph below, set error_y = list(type = "data", array = c(YOUR_VALUES)) 1 error_y = list(type = "data", array = c(YOUR_VALUES))
It is also possible to calculate and plot error bars with a percent value, like on the Rain line below. Set: error_y = list(type = "percent", value = CHOOSE_%_VALUE) 1 error_y = list(type = "percent", value = CHOOSE_%_VALUE) To create horizontal error bars use error_x. Furthermore, it's easy to graph asymmetrical error bars. Just set symmetric = FALSE and add an arrayminus array like this: error_x = list( type = "data", symmetric = FALSE, array = c(YOUR_HIGH_VALUES), arrayminus = c(YOUR_LOW_VALUES)) 12345 error_x = list(type = "data",symmetric = FALSE,array = c(YOUR_HIGH_VALUES),arrayminus = c(YOUR_LOW_VALUES)) Creating dashboards or visualizations at your company?
