Create a variable based on another in R

Question

In R Studio, I would like to add a column which is "percentage of maximum load" (see on the pictures), based on the relative load in the same line, and the highest four-line value in the load column. Here the maximum should be "115" in the data.

Answer 1

If I understand well, you could simply do something like that:

data$Percentage <- data$Load / max(data$Load)
