Research direction

Start by reproducing the tutorial's two heatmap.3 calls with the shown CNA.test and tumor.mat inputs, then inspect whether the matrices passed to heatmap.3 are numeric and whether the plotting device can accommodate the requested margins. Done means both tutorial heatmaps render without the numeric-matrix or figure-margins errors.

Description

Hi, I am using the code provided in the tutorial and cannot to generate both heatmaps using the following code

heatmap.3(t(as.matrix(CNA.test[,4:ncol(CNA.test)])),dendrogram="r", distfun = function(x) parallelDist::parDist(x,threads =4, method = "euclidean"), hclustfun = function(x) hclust(x, method="ward.D2"),
            ColSideColors=chr1,RowSideColors=cells,Colv=NA, Rowv=TRUE,
            notecol="black",col=my_palette,breaks=col_breaks, key=TRUE,
            keysize=1, density.info="none", trace="none",
            cexRow=0.1,cexCol=0.1,cex.main=1,cex.lab=0.1,
            symm=F,symkey=F,symbreaks=T,cex=1, cex.main=4, margins=c(10,10))

  legend("topright", paste("pred.",names(table(com.preN)),sep=""), pch=15,col=RColorBrewer::brewer.pal(n = 8, name = "Dark2")[2:1], cex=0.6, bty="n")

The error shows:

Error in heatmap.3(t(as.matrix(CNA.test[, 4:ncol(CNA.test)])), dendrogram = "r", :
`x' must be a numeric matrix

I also tried code to plot tumor heatmap:

heatmap.3(t(tumor.mat),dendrogram="r", distfun = function(x) parallelDist::parDist(x,threads =4, method = "euclidean"), hclustfun = function(x) hclust(x, method="ward.D2"),
            ColSideColors=chr1,RowSideColors=cells,Colv=NA, Rowv=TRUE,
            notecol="black",col=my_palette,breaks=col_breaks, key=TRUE,
            keysize=1, density.info="none", trace="none",
            cexRow=0.1,cexCol=0.1,cex.main=1,cex.lab=0.1,
            symm=F,symkey=F,symbreaks=T,cex=1, cex.main=4, margins=c(10,10))

  legend("topright", c("c1","c2"), pch=15,col=RColorBrewer::brewer.pal(n = 8, name = "Dark2")[3:4], cex=0.9, bty='n')

Another error occurs: Error in plot.new() : figure margins too large

Can you help?
