## Not run: 
 x <- read_STAR( pattern=".star.out$")
  reads <- c("Uniquely mapped",  "Mapped to multiple loci",
               "Mapped to too many loci", "Unmapped reads")
  y <- filter(x, stat %in% reads) %>% mutate( stat= factor(stat, levels=reads ))
         hchart(y, "bar", x=sample ,  y=value, group=stat ) %>%
            hc_plotOptions(bar = list(stacking = "normal")) %>%
             hc_colors( c('#437bb1', '#7cb5ec', '#f7a35c', '#b1084c') ) %>%
               hc_yAxis(reversedStacks = FALSE)
 read_STAR( pattern=".star.out$", reshape=TRUE)
