"cannot allocate memory block" using R plot.phylo
<p>I'm pretty new to R, and am trying to plot a phylogenetic tree with 75 tips and 73 internal nodes (for the first time). I have genotype data for 4567 SNPs.</p>

<p>When I try to plot the data, I get the following error message:</p>

<pre><code>&gt; 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*
</code></pre>

<p>What am I doing wrong here? It can't possibly need this amount of memory</p>
