R help - Jan 2015 - Question abt 'factanal' function

Hi,

I tried to run 'factanal' function for Factor Analysis, but failed to
get
results.

The error message was following,

Error in factanal(data, factors = 3, rotation = "varimax") :
  unable to optimize from this starting value

I searched for the solution of this error, and one said putting
'control=list(trace=T)' in the argument as

option, but it also failed. looks like no way for it on my own.

I doubted that high correlation btw observed variables in the original
data, so removed some

variables with high correlations (1~3, 19, 23~33). After that, I ran it ,
but also couldn't get any output.

If you respond to my question, it will a big help for me .

Hi

here are few points but no answer

Please
- do not use HTML post
- provide some example code and data (preferably by dput function) which
illustrate your point
- check your data by ?str if they really are what you think they are
- be more specific in your statements, we do not know what do you mean by
"couldn't get any output"

Cheers
Petr
