Hi Hadley, Thanks for the help. I found the problem. In the code you sent me earlier to correct the scale_y_continuous, (below) the parameter is "limits", rather than "limit", as you write it. If I run my code without introducing the change you sent me, it works, but if I first correct it, th

Hi Hadley, Well, the problem seems to be that ggplot is not recognizing the scale when set by scale_y_continuous, the maximum value stays exactly at the data range, irrespective of what I provide as range. I am not familiar yet with proto, therefore I do have some difficulty delving into the co

Hi Pedro, What's the problem exactly? You'll need to compute the range yourself, and then use scale_y_continuous as you have below. (Also you can abbreviate the bar chart plotting command to: qplot(x, y, data=plotdata, geom="bar", stat="identity")) Hadley On 12/11/07, Pedro de Barros <[EMAIL P

[R] ggplot - Setting the y-scale in a bar plot

2007-12-11 Thread Pedro de Barros
Dear All (probably Hadley), I am now trying to customise some plots using a bar geom. I do not want to use the default binning statistic, but rather calculate the bar heigths separately. I do manage this, but for comparison purposes I would like to have a set of plots all with the same y-axis
