[R] Error in Summary.factor(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 4L, : max not meaningful for factors

[Alex DJ]

Thanks Duncan. 

This is a package, SIAR. 

> fo <- ordered(f) 
 > fo 
[1] a b c d e 
Levels: a < b < c < d < e 
 > max(fo) 
[1] e 
Levels: a < b < c < d < e 

The data set has 101 values, what can I use instead of letters? 


Best wishes, 

Alex.
