Support for lp() function

[adityadey218]

Description

Hi, My R script is giving me an expected result through RStudio but when I use the same script through the Qlik Sense Load Editor, it is giving me an error saying there might be NA/NaN in the data being passed.

Steps to Reproduce

library(xlsx);
library(lpSolve);
q = read.csv(file = 'var140.csv', header = FALSE)
q = as.data.frame(q);
Constraint = q[2:168,1:140];
OBJ = t(q[2:141,142]);
RHS = t(q[2:168,141]);
BackToGeo = (lp("max", OBJ, Constraint, "<=", RHS, compute.sens = TRUE))$solution;
BackToGeo;

Expected behavior

A result vector of size 140 to be returned.
[What you expected to happen]

A result vector of size 140 to be returned.

Actual behavior

Argument 3 returns NA/NaN/Inf error
