"zud", "dru"), row.names = c(NA, 60L), class = "data.frame")
そしてこのコード：
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")))
そして、それは私にこの正しいプロットを与えます:
しかし、このコードスニペットを変更して正方形を三角形に変更しようとすると
+ scale_shape_manual(values=c(21,22))
の中へ
+ scale_shape_manual(values=c(21,24))
形状の凡例が正しくありません (2 番目の形状は空です)。
この塗りつぶされた形状の正しい凡例の形状を取得するにはどうすればよいですか? (Windows 64 ビット マシンで ggplot2' バージョン 0.9.3.1 および R 3.0.1 を実行しています)
