标签： r ggplot2 facet-wrap

我正在尝试使用数据框dataw创建一个facet wrapped ggplot boxplot，我正在尝试修改每个子图的标签。

dataw <- structure(list(base = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 
1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L,

                 geom_boxplot() + 
                 facet_wrap(type ~ pos, scales="free_y", nrow = 2) + 
                 theme_gray() %+replace% prettify

目前，子标签是type值，后跟逗号和pos值。但是我想摆脱类型值，并标记它，以便每个子图的标签格式为：“Position [pos value]，[labels value]”

尝试用

替换整个ggplot语句 
ggplot(data=transform(dataw, plt_labels = paste("Position ", pos, ", ", labels, sep="")),aes(x = base, y = values, color = type, group = base)) + 
  geom_boxplot() + 
  facet_grid(type ~ plt_labels, scales="free_y") + 
  theme_gray() %+replace% prettify

应该给出
