Howdy, I am trying to make a simple monochrome heatmap from 1 row of data. Essentially, I just want a long bar where black represents the max value in the data, white is the minimum, and all values in between are interpolated appropriately. I have tried using heatmap and heatmap.2, but both have issues. heatmap seems to be restricted to only drawing a square plot, and this data requires a long, thin plot (e.g. 50px tall by 3000 px wide). For heatmap.2, the plots will draw the dimensions I prefer, but when I do a small sample the coloring seems to not correlate with the data even though I have Rowv and Colv both set to FALSE. Any recommendations about the best way to make a clean, simple heatmap from a single array of positive integers would be greatly appreciated.
