[R] ace error because of missings?

[Birgitle]

Hello RUser!

I try to use ace for an ancestral state reconstruction but got back an error
message.

     ace(FacVar,Tree, type="discrete")

Warning messages:
1: In nlm(function(p) dev(p), p = rep(ip, length.out = np), hessian = TRUE)
:

number)

RestioTreeOoutgrBLrooted,  :
  The likelihood gradient seems flat in at least one dimension (gradient

I presume it is due to my missing values?

     na.pattern(dataframe)
    #dataframe contains 7 discrete characters. I get an error message with
all of them

pattern
0000000 0000001 0000100 0010000 0100000 1000000 1001000 1100100 1111111

1            1            4 

Can I fix this somehow?

Thanks in advance

Birgit
