I performed an MFA with FactoMineR and obtaines the following warning message
1: In doTryCatch(return(expr), name, parentenv, handler) :
zero-length arrow is of indeterminate angle and so skipped
2: In doTryCatch(return(expr), name, parentenv, handler) :
zero-length arrow is of indeterminate angle and so skipped
But I don't understand its meaning and how I could resolve this problem.
Could you help me please ?
