xyplot（）の背景色を変更する

Question

私はストリップの背景色を変更しようとしています（これは6x6マトリックスで、6つのストリップカラーはcolaという名前のベクターに保存されています）。私はインターネット上で見つけたものを組み合わせようとしましたが、私は完全にマークから外れてしまいました：今のところ、縦のストリップはすべて黄色で、水平のものはすべて赤です:(

Answer 1

このコード（私の答えからすぐにthis SO questionに適合）は、ソリューションへの道のりの一部になります（私は、それが各ストリップのテキストを印刷するのに適しているかどうかを学ぶことに興味があります）。

カスタマイズしたストリップ関数は、bwplot()へのネストされた呼び出しではなく、useOuterStrips()に直接渡す必要があることに注意してください。

# Create a function to be passes to "strip=" argument of xyplot 
myStripStyle <- function(which.panel, factor.levels, ...) { 
    panel.rect(0, 0, 1, 1, 
       col = bgColors[which.panel], 
       border = 1) 
    ## This call to panel.text() commented out because it does not 
    ## work as I would have expected/hoped it to 
    # panel.text(x = 0.5, y = 0.5, 
    #   font=2, 
    #   lab = factor.levels[which.panel], 
    #   col = "black") 
} 

mycola <- rainbow(6) 
bgColors <- mycola 

useOuterStrips(bwplot(~B$ylab|B$g1*B$g2,ylab="",xlab="",as.table=TRUE, 
         panel=function(...,bg){ 
          panel.fill(col=mycol[panel.number()]) 
         }, 
         scale=list(draw=FALSE)), 
       strip = myStripStyle, 
       strip.left = myStripStyle)
