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.

Cheers,

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
