Hello R-help. I am trying to make a stacked barplot where the color of the sections of each bar depend on another variable.
> myData[1:11,] score percent marker cellType Malignant 1 0 100.00000 ESR1 (ER) Bladder.M(5) TRUE 2 0 80.00000 PAX8 Bladder.M(5) TRUE 3 1 20.00000 PAX8 Bladder.M(5) TRUE 4 0 100.00000 ESR1 (ER) Brain.N(3) FALSE 5 0 100.00000 PAX8 Brain.N(3) FALSE 6 3 100.00000 ESR1 (ER) Breast.M(11) TRUE 7 0 100.00000 PAX8 Breast.M(11) TRUE 8 0 36.36364 ESR1 (ER) Cervix.M(11) TRUE 9 1 9.09091 ESR1 (ER) Cervix.M(11) TRUE 10 2 18.18182 ESR1 (ER) Cervix.M(11) TRUE 11 3 36.36364 ESR1 (ER) Cervix.M(11) TRUE palette <- palette(gray(seq(0, 1,len=4))) trellis.par.set(list(par.xlab.text=list(cex=0.85) , superpose.polygon=list(col=palette()) , axis.text=list(cex=0.8))) barchart(percent~cellType|marker , groups=score , data=myData , stack=TRUE , xlab='N=Normal/Benign, M=Malignant' , ylab='Percentage of Cores Staining' , color=palette() , auto.key = list(points = FALSE, rectangles = TRUE, space = "top") , scales=list(x=list(rot=70)) , layout=c(1,2)) I would like to make the color scheme of the bar differ according to the variable 'Malignant' and add a second color scheme to the key.
