Ok,
This really helped.
You've probably noticed, I'm a begginer using R.
And when you said that you tried with rnorm and the counts were not zero,
where did you use the rnorm?
Where the runif is, in its stead use

Hi,
I'm Wellington from Brazil and I have the following issue:
I've been working on a project a for a while, and I'm having trouble in
using the loop (for)
I need to read a column (c1), and for each value of this column, I need to
check if it's within the control limits
So, I was
Hello,
Your code example doesn't make much sense, it needs decrypting. Let's see,
for(k in 1:length(c1)){
if(c1[k] lcl | c1[k] ucl) {do something}
}
If this is it, then you can completely avoid the loop:
i1 - c1 lcl | c1 ucl # create an index vector
out.of.control - c1[ i1 ]
Hello,
Try the following.
# make up some data
dds - 1e3
nc - 10
xss - data.frame(matrix(runif(nc*dds, min=-1, max=1), ncol=nc))
names(xss) - paste0(xs, 1:10)
# two functions with descriptive names
getControlLimits - function(x, L = 3){
mu - mean(x)
sigma - sd(x)
c(lcl = mu -
