the first name of the first column

md <- as.matrix(d[,-1])  ## knowledge of indexing is essential in R !
md

is.numeric(md)

dimnames(md)[[2]] <- NULL
md

I am sorry. Her is the reproducible data

structure(list(region = structure(c(1L, 1L, 1L, 1L), .Label = "zilan",
class = "factor"),
    Fe_ppmtp = c(8.36, 8.78, 16.52, 42.22), Zn.ppmtp = c(0.44,
    0.58, 2.28, 14.22), Mn_tp = c(6.9, 21.16, 27.58, 34.7), Cu_tp = c(0.5,
    0.24, 0.8, 31.9)), class = "data.frame", row.names = c(NA,
-4L))

Hi Brent;

Thanks so much, fore writing. It is much appreciated. Here is a small
example from my data

Bolge Fe_ppmtp Zn ppmtp Mn_tp Cu_tp
zilan
zilan 8.36 0.44 6.9 0.5
zilan 8.78 0.58 21.16 0.24
zilan 16.52 2.28 27.58 0.8
zilan 42.22 14.22 34.7 31.9

Clarification needed.

Are your data in a data frame or an alphanumeric matrix? What does it
look like?

A small reproducible example would be very useful here I think!

Also, is this relevant:

d <- matrix(1:12,ncol = 4)
d

     [,1] [,2] [,3] [,4]
[1,]    1    4    7   10
[2,]    2    5    8   11
[3,]    3    6    9   12

dd <- d[,c(3,1,2,4)]
dd

     [,1] [,2] [,3] [,4]
[1,]    7    1    4   10
[2,]    8    2    5   11
[3,]    9    3    6   12

Perhaps you neeed to spend time with an R tutorial that covers indexing
of data frames and matrices, an absolutely basic R operation? (I am not
clear from your question if this is your problem).


Cheers,
Bert

Dear all;

I need to run heatmap. Because my first column in my data is
alphanumeric,
I can not run as.matrix(scale(my_data)). So I need to make my data
readable
as in data(mtcars). In *mtcars *data the first column is alphanumeric
and
has no  name.

Thanks,

Greg
