Has anyone successfully created a PNG file for a dendrogram? I am able to successfully launch and view a dendrogram in Quartz. However, the dendrogram is quite large (too large to read on a computer screen), so I am trying to save it to a file (1000x4000 pixels) for viewing in other apps. However, whenever I try to initiate a PNG device, I get a "need finitite 'xlim' values" error.
Here is some example code to illustrate my point: cor.matrix <- cor(mydata,method="pearson",use="pairwise.complete.obs"); distance <- as.dist(1.0-cor.matrix); hc <- hclust(distance); p <- plot(hc); plot(p); #This works! Plot is generated in quartz no problem. #Now, try this: png(filename="delme.png",width=4000,height=1000); cor.matrix <- cor(mydata,method="pearson",use="pairwise.complete.obs"); distance <- as.dist(1.0-cor.matrix); hc <- hclust(distance); p <- plot(hc); plot(p); #Error in plot.window(...) : need finite 'xlim' values #In addition: Warning messages: #1: In min(x) : no non-missing arguments to min; returning Inf #2: In max(x) : no non-missing arguments to max; returning -Inf #3: In min(x) : no non-missing arguments to min; returning Inf #4: In max(x) : no non-missing arguments to max; returning -Inf This is the exact same code, only a prior call to png() causes the seemingly unrelated xlim to fail. Why is this?
