Try to convert the dataframe in a matrix:

z<-as.matrix(yourdataframe)
sort(z)

It would run!

Hi all 

I have the next data frame 

    year   STOD    SLAGNR  TAL TALT   TALVEKT
1 2002  2120006     57      1      NA      1
2 1997  97030032    57     NA   NA      NA
3 1997  97030071    27     1      NA      NA
4 1997  97030005    57     1      NA      NA
5 1997  97020127    60     NA   1         NA
6 2001  1160025     27      1      NA      1
7 1998  98020069    60     1      NA      NA
8 1996  96030009    57     NA   1         NA

How to sort it according to "year" column
Sort does seem to work only on vectors

Thank you
