[R] help with heatmap - how to remove annoying "X" before numeric values?

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", labColNULL, 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

read.table is doing that, not heatmap.2.  Use
   read.table("temp.txt", header = TRUE, check.names = FALSE)

[R] help with heatmap - how to remove annoying "X" before numeric values?

Hi Suzanne,

My solution (which I am sure is not the best) would
be:
> heat <- read.table('temp.txt')
> heat      X1905 X1910 X1950 X1992 X2011 X2020
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  0.50  0.59> a<-names(heat)

""     "1950" ""
"1992" ""     "2011" ""    
"2020"> z <- w[seq(2,length(w),by=2)]
> z[1] "1905" "1910" "1950" "1992"
"2011" "2020"> names(heat) <- z

[R] help with heatmap - how to remove annoying "X" before numeric values?

Sorry, I just realized I didn't send this to the list! (See below)

Thanks for all the help! All is working fine now.

If anyone knows of a more straightforward way to change the "Value"
string
for the Key, please let me know (just to satisfy my curiosity).  I got it to
work by modifying the source code (specifically, "heatmap.2.R " in the
gplots package).

However, before, I didn't make the call
source("heatmap.2.R")

before I called
source("mysillyheatmap.R")

Making the additional call to " heatmap.2.R" fixed everything.

Thanks again for all your help!
