Dear All,
 
While inverting a matrix the following error appears on my console:
 
Error in solve.default(my_matrix) : Lapack routine dgesv: system is exactly singular
 
With this respect, I have been replacing the solve() function with ginv(): the Moore-Penrose generalized inverse of a matrix. 
 
These are the questions I would like to ask you:
 
1. Would you also replace solve() with ginv() in these scenarios and using R? 
2. Or is there something I should take care by using ginv() you would suggest me please? 
 
Many thanks in advance.
 
Best regards,
Werner
