Hi All

I plot the heat map for my logCPM successfully but using Ensemble geneIDs. I need the heatmap to have the gene symbols, I can convert the ensemble gene IDs to gene IDs fine, but don't know how to reflect this on the heatmap. My code for the heatmap and my code for ensemble IDs to gene sybmol are below if any one can help where can I reflect the gene symbol in the heatmap, thanks very much

Heatmap

    logCPM =countsPerMillion
    o = rownames(etp$table[abs(etp$table$logFC)>2 & etp$table$FDR<0.01, ])
    logCPM = logCPM[o[1:25],]
    colnames(logCPM)  = LABELS
    logCPM = t(scale(t(logCPM)))
    require("RColorBrewer")
    require("gplots")
    myCol <- colorRampPalette(c("dodgerblue", "black", "yellow"))(25)
    myBreaks <- seq(-3, 3, length.out=26)
    heatmap.2(logCPM, col=myCol, breaks=myBreaks,symkey=F, Rowv=TRUE,Colv=TRUE, main=title, key=T, keysize=0.7,scale="none",trace="none", dendrogram="both", cexRow=0.7, cexCol=0.9, density.info="none",margin=c(10,9), lhei=c(2,10), lwid=c(2,6),reorderfun=function(d,w) reorder(d, w, agglo.FUN=mean),  distfun=function(x) as.dist(1-cor(t(x))), hclustfun=function(x) hclust(x, method="ward.D2"))

Naming conversions:

library(EnsDb.Hsapiens.v79) 
geneIDs <- ensembldb::select(EnsDb.Hsapiens.v79, keys= o, keytype = "GENEID", 
columns 
= c("SYMBOL","GENEID"))

Thanks all
