[Gretl-devel] a small generalization of the replace() interface

Hi, the replace() function takes as 2nd and 3rd arguments the mapping pairs of values. What about enabling a little bit of syntactic sugar for the case of a matrix with exactly 2 columns, standing in for the respective vectors, making the 3rd argument optional in cases like the following example: matrix m = {3, 0.5; 2, 0.7}    # arbitrary stuff for the example series y = replace(x, m)      # not working yet which would be equivalent to: series y = replace(x, m[,1], m[,2]) BTW, thinking about this, there seems to be some similarity to the strsub() function. What I mean is that replace() could be overloaded to nest the usage of strsub(), based on the type of the first argument. And strings arrays might be supported as arguments as well. This is just a general observation, I don't have a concrete need right now, but I guess there would be use cases, replacing some handwritten loops. Does replace() actually work already on a string-valued series? If not, I guess it should? thanks sven
