Can I use this Grouped bar function without having Image processing toolbox? Errbar R I used the following script: #barplot where x is the independent on the x-axis, y is the #dependent on the y-axis and z is the independent given by #different colored bars Let me first thank you for this function! Unfortunately, I do not have R2015a and am therefore unable to debug the graphical display problems that cropped up in the function following the R2014b update and its overhaul of graphical

However, it will be fantastic to understand how or why the following lines of code work:groupwidth = min(0.8, numbars/(numbars+1.5)); andx = (1:numgroups) - groupwidth/2 + (2*i-1) * groupwidth / (2*numbars); Thank It's a lot of code written for a relatively small return. 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, news If you only are working with between-subjects variables, that is the only function you will need in your code.

Line 254-257: he_xdata(4:9:end)=he_xdata(1:9:end)-errorbar_width*bar_width/2; he_xdata(7:9:end)=he_xdata(1:9:end)-errorbar_width*bar_width/2; he_xdata(5:9:end)=he_xdata(1:9:end)+errorbar_width*bar_width/2; he_xdata(8:9:end)=he_xdata(1:9:end)+errorbar_width*bar_width/2; Making the change that he suggests did not solve the problem for me. Scatter Plot With Error Bars In R In our group, Ecology and Biodiversity, we started using R for statistical analyses. with mean 1.1 and unit variance.

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

The following is an example of this:model_series = [10 40 80; 20 50 90; 30 60 100]; model_error = [1 4 8; 2 5 9; 3 6 10]; h = bar(model_series); Discover...
