顯示在GGPLOT2的傳說正確的填充形狀

Question

我有以下數據集：

structure(list(com = c("v", "v", "v", "v", "v", "v", "v", "v", 
"v", "v", "v", "v", "v", "v", "v", "v", "v", "v", "v", "v", "v", 
"v", "v", "v", "t", "t", "t", "t", "t", "t", "t", "t", "t", "t", 
"t", "t", "t", "t", "t", "t", "t", "t", "v", "v", "v", "v", "v", 
"v", "t", "t", "t", "t", "t", "t", "t", "t", "t", "t", "t", "t" 
), d = c(0.85, 0.85, 0.85, 0.85, 0.85, 0.85, 0.85, 0.85, 0.85, 
0.85, 0.85, 0.85, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,

), dru = c(420, 540, 420, 370, 280, 170, 410, 250, 440, 580, 
710, 530, 360, 300, 270, 240, 190, 190, 290, 270, 380, 330, 
450, 480, 320, 320, 285, 285, 190, 190, 290, 290, 420, 420, 
450, 450, 310, 300, 270, 230, 210, 210, 345, 305, 250, 270, 
205, 205, 290, 310, 270, 280, 270, 260, 340, 350, 420, 410, 
510, 500)), .Names = c("com", "d", "strf", "side", "auf", 
"zud", "dru"), row.names = c(NA, 60L), class = "data.frame") 

和驗證碼：

s <- ggplot( data2 , aes(zud, dru)) 

s + geom_point(aes(shape=com, size=strf, fill=as.factor(d)) , alpha=0.5) + 
    scale_fill_hue( h=c(90, -100), l=seq(80, 20,length.out = 5), c=90) + 
    scale_size(range = c(2 , 10)) + 
    ylim(100, 700)  + scale_shape_manual(values=c(21,22)) + 
    facet_grid(side ~ auf) + 
    guides(fill = guide_legend(override.aes = list(shape = 21, size=5)),  
      shape = guide_legend(override.aes = list(size=5)), 
      size = guide_legend(override.aes = list(shape=21, fill="grey70"))) 

這一點讓我這個正確的陰謀：

但是，當我嘗試通過更改此代碼將方形更改爲三角形代碼段

+ scale_shape_manual(values=c(21,22)) 

成

+ scale_shape_manual(values=c(21,24)) 

對形狀傳說是不正確的（空的用於第二形狀）。

我應該怎麼做才能得到正確的傳奇造型爲這個填充形狀？ （我在Windows 64位機器上運行ggplot2'版本0.9.3.1和R 3.0.1）

重新啓動R和ggplot2後，圖例正確顯示。
