[R] Vary an equation using values from a sequence
Hi All, I have a vector of data on which I am operating. The equation with which I want to operate on the vector has a value k. I want to run the equation and output a new vector, each time replacing k with each value from the sequence I defined. I have thought about using for loops and such, but this seems like overkill. I am wondering if there is a simple solution that would allow me to accomplish this. The code I am using is outlined below. Data <- c(1:10) #Data value <- seq(from = 0, to = 100 , by = 0.01) #Sequence Data - min(Data) + k # Equation Thanks, Jake Jake Andrae PhD Candidate Geology & Geophysics ?

I thnk what you want is ?outer. e.g.: outer(Data -min(Data),value,FUN = "+") Whether this works for your real task, however, may depend on details and complexities that you have omitted.
