I'm trying to write a for-loop that finds the high tide in a vector of 10-minute tide recordings. When it finds the high tide, I'd like it to spit that value into a new vector. I generated some simple sample data (attached) that simulates the dataset with integers. So far, I have:

d <- read.csv("numbers.csv", header=T)

m=0

for (i in 1:length(d$numbers)) {

if(d$numbers[i]>=m) {d$numbers[i] -> m} 

else {m=m}

}
