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) [[alternative HTML version deleted]]

Hi I have a problem in R that I have been trying to solve but without success. I am trying to join two tables on two variables : an ID and a date (optional) that will be common between the two tables In SQL (and SAS PROC SQL) I am a frequent user of the "select" command and I am used to the following nomenclature : select a.*, b.c, b.y, b.z from table1 a, table2 b where
