Suppose that i want to find $x$ whith minimum 2-norm such that $Gx >= f$ : i'll use lsei::ldp to do that (see https://cran.r-project.org/web/packages/lsei/lsei.pdf page 4-5-6).

What if i want to find $x$ with minimum 1-norm such that $Gx >= f$ ?

By 1-norm, i mean sur sum of absolutes values of composants of a vector, and by 2-norma i mean the sum of squares of composants of the same vector.

I'm pretty shure this problem is implemented somewhere in CRAN but i cant find it.
