dataframe - Factor Analysis in R, Error -


i have typed following command in r

factanal(td, factor = 10, rotation = "varimax", scores = "regression")

where td data frame containing 41 variables

i getting following error

error in factanal(td, factor = 10, rotation = "varimax", scores = "regression") : unable optimize starting value

can me error.

i have had same problem, found adding control argument "lower", specifies lower bound uniqueness (default = 0.005), helps!

for problem value of 0.00000001 gave results. afterwards, turned out had variables low values of uniqueness. might have created 4 dummies factor 4 levels, thereby creating redundancy.

so tips: 1. play lower argument 2. once works, check variables have low uniqueness, take them out of dataframe & run factor analysis again
