[R] Issues with Heat Map Images

[cpleisner]

David,
Thanks for the help.  I tried the following code:

heatdata <- read.csv("logFC_bin17.csv", sep=",")
heatdata <- heatdata[,2:5]
heatdata_matrix <- data.matrix(heatdata)
rownames(heatdata_matrix) = paste("Gene", 2:655)
jpeg("Heatmap_bin17.jpeg", width=8, height=8, units="in", res=300, 
quality=100) 
data_heatmap <- heatmap.2(heatdata_matrix, col=redblue(75), scale="row", 
key=TRUE, symkey=FALSE, density.info="none", trace="none", margins=c(10,10), 
cexRow=0.5) 
axis(4, 
      at=1:NROW(heatdata_matrix), 
      labels=rownames(heatdata_matrix[data_heatmap$rowInd] ), 
      cex=0.5) 
dev.off() 

It solved the issue with the jpeg, but I am still getting the following
image:
<http://r.789695.n4.nabble.com/file/n4648906/Heatmap_bin17.jpeg> 

The axis labels are still off and now there is this '1' in the upper right
hand corner.  Thoughts?
Courtney
