在Canvasxpress中使用R更改Scatter3d的颜色

Question

在这个网站(https://cran.r-project.org/web/packages/canvasXpress/vignettes/getting_started.html#scatter-3d-plot)的第一个例子中，有一个3d散点图，是用R。

只需复制和粘贴代码，您就可以轻松获得示例的结果……

data <- t(iris[,1:4])
varAnnot <- as.matrix(iris[,5])
colnames(varAnnot) <- "Species"
canvasXpress(t(data), varAnnot=varAnnot, graphType='Scatter3D', colorBy='Species')

我想知道是否有一种方法可以在canvasXpress(t(data), varAnnot=varAnnot, graphType='Scatter3D', colorBy='Species')中传递这样的参数：

canvasXpress(t(data), varAnnot=varAnnot, graphType='Scatter3D', colorBy='Species', colors="rgb(153,204,255)","rgb(204,102,0)","rgb(153,76,0)","rgb(169,131,7)","rgb(153,255,153)","rgb(105,150,150)","rgb(183,120,68)","rgb(131,172,208)","rgb(194,224,118)","rgb(250,220,90)","rgb(255,84,159)","rgb(255,175,84)","rgb(154,184,183)","rgb(210,166,131)","rgb(61,105,155)","rgb(135,172,34)","rgb(205,169,8)","rgb(208,33,88)","rgb(208,115,0)","rgb(86,118,118)")

为了改变图中点的颜色...

我尝试在generated...specifically的菜单栏中更改颜色参数(设置一个新的RGB颜色数组)，然后使用ctrl + alt + R重现changes...but。

对此有什么想法吗？

谢谢

传入一个colorKey：

colorKey = list("Species"=list("setosa"="gold","versicolor"="silver","virginica"="red"))

然后打电话给：

data <- t(iris[,1:4])
varAnnot <- as.matrix(iris[,5])
colnames(varAnnot) <- "Species"
canvasXpress(t(data), 
    varAnnot=varAnnot, 
    graphType='Scatter3D', 
    colorBy='Species', 
    colorKey=colorKey)
