  4. The values for the y vector are trivial, since these are just our mean values, we computed above.
  5. If you want y to represent counts of cases, use stat="bin" and don't map a variable to y.

If I did not need error bars I could adapt this script but the tricky part is to mix ggplot beautiful barplots and error bars! ;) If you have any idea Instead of columns of means, we just need to supply barplot() with a matrix of means. The standard error is then adjusted to the level of trust you want to have for your approximation (mostly 95%) by multiplying it with the confidence coefficients for the normal distribution. this contact form Note that tgc$size must be a factor.

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. with mean 1.1 and unit variance. Now we have all parameters for the errbar function.
