[R] Canonical Correspondence analysis-CoCoAn package

[srinivasa raghavan]

Hi R-users,

   I am new to R environment.I want to carry out a
correspondence analysis on a contigency table with 64
columns and 298 observation of Environmental data.In
many cells of the contigency table the frequency is
just the value '1'.

I got the  following error.


> CAIV(Eplankton)
Error in if (L[i, j] < 0) return("Table L must contain
non-negative numbers") : 
        missing value where logical needed
In addition: Warning message: 
"<" not meaningful for factors in:Ops.factor(L[i,j],0)


Any suggestion on what went wrong.

Thanks in advance

srinivas
