Try this and see how fast it runs:

Try this and see how fast it runs:
# x is your input matrix that will be processed by column

y <- t(apply(x, 2, function(.col){

(.col - .rang[1]) / (.rang[2] - .rang[1]) * 100

Here's my code:
nc<-ncol(mat) #setting end point in counter to number of cols in sm
nr<-nrow(mat)
mm <- array(NA, dim=c(2, nc)) #to hold min/max ranges
sc <- array(NA, dim=c(nr, nc)) #to hold percentile scales
for (n in 1:nc) { #now calculate respect
I am trying to apply the solution you mentioned to all columns in a matrix,
and output the results to another matrix and append the two using the cbind
function.
I have written something that works, using a nested For loop to go through
all the cells in the target matrix, but the trouble is that
Thank you Ben! This is very clear.

Hi Ben,
Yes, this is more or less what I want to do. I want to apply this data in
columns in a matrix, and insert the results to additional columns. I am not
entirely aware of a good way of doing this.
e.g. take data from column B, apply normalisation, and feed output into
column C
Thanks,

Hi everyone,
I want to score a set of data (-ve to +ve) using a 0-10 scale. I
have the
data in an R matrix, so I need to add another column, containing
the scores
and resave.
Hi,
I am a little fuzzy on what you are asking, but my guess is th
