Dear all,

I want to have a matrix of 100 elements.
Each element must be a vector of 500 elements.
If I do:
imp-array(dim=100)
imp[1]-vector(length=500)
it does not work. Warning message: number of items to replace is not a
multiple
For the case someone is interested in it, here it is the solution

imp - vector(list, 100)
imp[[1]] - im[1:500,]
names(imp[[1]]) = the list of labels of imp[1:500,]

Hello everyone
Could anybody tell me how to set the following matrix?
n2-matrix(nrow=10185,ncol=10185,seq(0,0,length=103734225))
R answer was
Error: cannot allocate vector of size 810423 Kb
Are there any solution? I tried to increase the memory size but it didn't work

You can use:
library(SparseM)
as.matrix.coo(0,10185,10185)
but then you need to find something
Dear R Users,
I have a matrix A, and I want to change every value of this matrix if these
values are greater than an assuming value. For a vector it is simple, e.g.
a-c(1:10); a[a5]-0.
Of course, I can change matrix to vector, assign a value then change vector to
matrix. But does there exist

Hello,
This should be a fairly simple question. I have 2 matrix's and I want to get
the difference between them and then remove the difference from one of them.
So A vs B, anything I see in B I want to remove from A, and then print out
the final matrix.
I have some code here but at the moment
this and remove that row from matrix A.

When you're operating on each column of a matrix, you really should
consider the apply() function, which was written for the task. Also,
it's usually easier to count things in R by taking the sum of a logical
expression, rather than the length of a
