Hello All,

I have a simple question based on how things are labeled on my heat map;
particularly, there is this annoying "X" that appears before the numeric
value of all the labels of my columns.

Let's say I have the following silly data, stored in "temp.txt"
        1905    1910    1950    1992    2011    2020
Gnat    0.08    0.29    0.29    0.37    0.39    0.43
Snake   0.16    0.34    0.32    0.40    0.41    0.53
Bat     0.40    0.54    0.52    0.60    0.60    0.63
Cat     0.16    0.27    0.29    0.39    0.37    0.41
Dog     0.43    0.54    0.52    0.61    0.60    0.62
Lynx    0.50    0.57    0.54    0.59    0.5     0.59

I use the following commands to generate my heatmap:
heat <- read.table('temp.txt')
x <- as.matrix(heat)

heatmap.2(x, keysize=1.2, dendrogram="none", trace="none", Colv = FALSE,
main = "Silly Data", labCol=
NULL, margin=c(7,8))

This generates a very nice heatmap, but there is one thing I have an issue
with: How do I get rid of the 'X' that seems to come automatically before my
numeric column values? I just want those columns to be labeled 1905, 1910,
1950, and so on. I cannot find anything in the heatmap.2 documentation that
suggests how I should do this.

Thank you very much for your time, and patience in reading this!

Sincerely,
Suzanne
