我是R的新手，我正在尝试使用75个提示和73个内部节点绘制系统发育树（这是第一次）。我有4567个SNP的基因型数据。
当我尝试绘制数据时，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？它可能不需要这么多的内存
