[R] problem with fitdistr ?

[Spencer Graves]

      Which version of R and the MASS library?  It worked for me just 
now with R 1.8.1: 

 > library(MASS)
 > fitdistr(rnorm(100),"Normal",start=list(mean=0,sd=1))
      mean          sd   
  0.03760724   0.97053743
 (0.09705374) (0.06862975)

      hope this helps.  spencer graves
