title: Error while creating heatmaps - NA/NaN/Inf in foreign function call (arg 11)
body: <p>I'm trying to prepare heatmap for my data but I have no idea why this error appears.</p>

  <p>The code which I use to create a heatmap (it works for other data):</p>
  
  <pre><code>## For all of the genes
  tbl_ready &lt;- as.matrix(tbl_for[,2:25])
  mode(tbl_ready)&lt;-"numeric"
  
  library(gplots)
  heatmap.2(tbl_ready,
            Colv = NA,
            scale = "none",
            dendrogram = "row",
            col=rainbow(256, s = 1, v = 1, start = 0, end = 2/6, alpha = 1),
            density.info = "none",
            trace = "none",
            key = FALSE,
            cexCol=0.5,
            cexRow=1)
  
  mtext(paste("ATh",""), side=3, line=-1, cex=1.5, col="black") 
  mtext("Size in kDa", side=1, line=3.5, cex=1.3, col="black")  
  </code></pre>
  
  <p>I even tried to replace Na/NaN/Inf to 0 to avoid problems:</p>
  
  <pre><code>## Replacing Na by 0
  is.na(tbl_ready) &lt;- sapply(tbl_ready, is.infinite)
  tbl_ready[is.na(tbl_ready)] &lt;- 0
  tbl_ready[is.nan(tbl_ready)] &lt;- 0
  </code></pre>
  
  <p>but the error still appears:</p>
  
  <pre><code>Error in hclustfun(distfun(x)) : 
    NA/NaN/Inf in foreign function call (arg 11)
  </code></pre>
