deleting invariant rows and cols in a matrix
Greetings,
I couldn't find any existing function that would allow me to scan a
matrix and eliminate invariant rows and columns so I have started to
write a simple routine from scratch. The following code fails because
the array index goes out of bounds for obvious reasons you'll see
shortly.
Start with some data
x <- read.table("myex.dat",header=T)
x
v1 v2 v3 v4 v5 id
