Re: [R] How to do a target value search analogous to Excel Solver

Hi, Try this: set.seed(1) z <- rnorm(1,0,1) y <- function(x, z, xc){2*x - 1 + z - xc} ## uniroot finds a 0 value, so offset function by 5.5 uniroot(y, z = z, xc = 5.5, interval = c(-100, 100)) ## use the root and now no offset y(3.563227, z, 0) see ?uniroot for help Cheers, Josh On Mon, Nov
