Hello R community, I am using R for creating a model using optimization. I would like to ask if there is R-function/package for solving the problem below: Minimize sum(abs(exp^(Ai1 x1 + Ai2 x2 + ... + Aim xm - bi) - 1)), for each i = 1, ..., n. subject to Ai1 x1 + Ai2 x2 + ... + Ajm xm - bi <= c, where c is a scalar. (x is a vector of variables, A is nxm matrix, b is a vector)

My R script needs to pause or wait for a key or mouse on each graph. I used the following statement after each plot par(ask=TRUE) This works on Windows but not on MacOS. Is there any way to pause on graph in MacOS? Thanks, Vu [[alternative HTML version deleted]]

Hello -- Is there any R function that implements Wrapper Subset Selection method? I am using 'leaps' package, and I do not know if 'leaps' works better than Wrapper. Thanks, Vu
