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
