Hello all,

I'm trying to plot a heatmap using the heatmap.2 function from the 'Gplots' package.I'm getting some unwanted white lines separating some of the rows and columns. Can somebody help me out to get rid of these lines? The code and the plot are as follows:

Thanks in Advance

heatmap.2(my.mat,
Rowv=TRUE,
Colv=FALSE,
dendrogram= c("row"),
scale="none",
distfun = dist,
hclustfun = hclust,
key=TRUE,
keysize=1,
trace="none",
density.info=c("none"),
margins=c(15, 20),
col=redgreen(75),
sepwidth=c(0,0),
cexRow=1.00    
)
