[R] ggplot seq

[Felipe Carrillo]

Thanks Thierry: 
The use of levels is what I needed, thanks for your help.

 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,
