我有警告按摩

 error in dev.off(): internal read error in PDF_endpage

在rstudio中创建PDF时。

PDF是关于共识聚类图的。我使用aheatmap（）函数创建它：

  pdf(file.path(fig.path, outFigFile), height=height)
  if(sum(hc.res$labels!=colnames(matrix.sum))>0) {stop("colnames mismatch for aheatmap!")}
  hv = aheatmap(as.matrix(matrix.sum), Rowv=as.dendrogram(hc.res), Colv=as.dendrogram(hc.res), annCol=annCol, annColors=annColors, revC=TRUE, fontsize=fontsize)
  invisible(dev.off())

如果用于绘制图形的matrix.sum相对较小，例如200行和列，则不会造成任何问题，并且可以成功创建PDF。但是当涉及到一个相对较大的矩阵（我在这里使用的是7820 * 7820）时，它就会显示警告消息。

我不知道该如何处理。你能给我任何可能的解决方案吗？
