failure to print summary() of an object - R
===

I'm having problems with `summary()`. At the moment I have 80 columns with 220, 000 rows of data, `multinom()` was used to perform a Multinomial Logistic Regression, the function performed fine however when I ran `summary()` on the regression, R does not print anything, it just sits there doing nothing until I press Ctrl-c.

    mod <- multinom(x ~ y, data = df)
    summary(mod) # does nothing

However if I just type in:

    mod

R prints the coefficients without the std-errors. Additionally using `allEffects()` from the `effects` package to display the effect of predictor variables, also "hangs"

    allEffects(mod) # does nothing...


What is happening? I have tried a smaller amount of data, and the above seems to work.
