[R] Standard Deviation of a matrix

[chakri]

Thank you everyone for your kind input,

I forgot to add that I have decimal points in my matrix !

Enclosed input file (reduced to 10 X 10 matrix), scripts and output for your
suggesions:

Code 1:
library(stats)
Matrix<-read.table("test_input", head=T, sep=" ", dec=".")
SD<-sd(as.numeric(Matrix))
SD

Output 1:
> library(stats)
> Matrix<-read.table("test_input", head=T, sep="\t", dec=".")
> SD<-sd(as.numeric(Matrix))
Error in sd(as.numeric(Matrix)) : 
  (list) object cannot be coerced to type 'double'
Execution halted

Code 2:
library(stats)
Matrix<-read.table("test_input", head=T, sep="\t", dec=".")
dim(Matrix)<-1
SD<-sd(Matrix)
SD

Output:
> library(stats)
> Matrix<-read.table("test_input", head=T, sep="\t", dec=".")
> dim(Matrix)<-1
Error in dim(Matrix) <- 1 : 
  dims [product 1] do not match the length of object [10]
Execution halted

Code 3:
library(stats)
Matrix<-read.table("test_input", head=T, sep="\t", dec=".")
SD<-sd(c(Matrix))
SD

Output:
> library(stats)
> Matrix<-read.table("test_input", head=T, sep="\t", dec=".")
> SD<-sd(c(Matrix))
Error: is.atomic(x) is not TRUE
Execution halted

Any ideas, what am I missing here ?

TIA
