Thanks Thierry: The use of levels is what I needed, thanks for your help.
From: ONKELINX, Thierry <thierry.onkel...@inbo.be> Subject: RE: [R] ggplot seq To: mazatlanmex...@yahoo.com, r-h...@stat.math.ethz.ch Date: Friday, January 23, 2009, 3:01 AM Dear Felipe, Provide a dummy sample if your dataset is big or confidential. The actual values are not that important to figure out what kind of plot you want. How did you code Week? Numeric? Try convert it into a factor with levels = c(27:52, 1:26). And then set the breaks to seq(1, 52, by= 2). WFBox <- data.frame(Week = rep(1:52, 10), FL = rnorm(520)) WFBox$fWeek <- factor(WFBox$Week, levels = c(27:52, 1:26)) library(ggplot2) ggplot(WFBox, aes(fWeek, FL)) + geom_boxplot(outlier.colour="pink",outlier.size=3,outlier.shape=21,fill= "goldenrod",colour="blue") + scale_x_discrete(breaks=c(seq(1,51,2))) HTH, Thierry ir.
