How do I get ggplot to order facets correctly?

Question

I am trying to facet about 14 plots based on a variable that runs from 2-14. The plots show up in the order: 10,11,12,13,14,15,2,3,4,5,6,7,8,9

How do I get them to order from 2-15?

update: ok, so I made it a factor using data$var=as.factor(data$var) . The Levels are Levels: 10 11 12 13 14 15 2 3 4 5 6 7 8 9

How do I reorder those?

Answer 1

data$var <- factor(data$var, levels = sort(unique(data$var)))

Answer 2

如果没有您的数据，我最好的猜测是将您的分面变量转换为具有您想要的级别的因子。
