The sd function doesn`t give the same results than older version, when it?s
applied to a data frame object and the object contains some character data.

Ex:
datos=data.frame( )
fix(datos)
          Grupo Vel 
          A     10.1       
          A     9.8            
          B     10             
          B     10             
          A     9.9           
          A     10.1          
          B     NA           
          A     10            

sd(datos,na.rm=T)
