r - “无法分配内存块”使用 R plot.phylo

Question

我对 R 很陌生，正在尝试绘制一个包含 75 个提示和 73 个内部节点的系统发育树（第一次）。我有 4567 个 SNP 的基因型数据。

当我尝试绘制数据时，我收到以下错误消息：

> plot(tre, type = "fan", use.edge.length = TRUE, node.pos = NULL, 
    show.tip.label = TRUE, show.node.label = FALSE, edge.color = "black", 
    edge.width = 1, edge.lty = 1, font = 3, cex = 0.3, adj = NULL, srt = 0, 
    no.margin = FALSE, root.edge = FALSE, label.offset = 0, underscore = FALSE, 
    x.lim = NULL, y.lim = NULL, direction = "rightwards", lab4ut = NULL, 
    tip.color = "black", plot = TRUE, rotate.tree = 0, open.angle = 0, 
    node.depth = 1, align.tip.label = FALSE)


Error in reorder.phylo(x, order = "postorder") : 
  cannot allocate memory block of size 67108864 *Tb*

我在这里做错了什么？它不可能需要这么多内存
