[adegenet-forum] error on find.clusters

[Willyard, Ann]

On my way to DAPC, I am stuck on an error finding clusters:
> grp <- find.clusters(a, max.n.clust=40)
Error in if (nf > rank) nf <- rank :   missing value where TRUE/FALSE needed

I imported an SSR matrix that has 1022 individuals, 6 loci, and 47 populations:
>df <- read.loci(file.choose(), loci.sep=",", col.pop=2, col.loci=3:8)
And created a Genuind object using
>loci<-df[,3:8]
>pop<-df[,2]
>sample<-df[,1]
>a <- df2genind (loci, ncode=3, sep = ",", missing = NA, ploidy = 1, >pop=pop, ind.names=sample)
And confirmed that it is in the correct format using:
print(a, details = TRUE)

   #####################
   ### Genind object ###
   #####################
- genotypes of individuals -

S4 class:  genind
@call: df2genind(X = loci, sep = ",", ncode = 3, ind.names = sample,
    pop = pop, missing = NA, ploidy = 1)

@tab:  1022 x 6 matrix of genotypes

@ind.names: vector of  1022 individual names
@loc.names: vector of  6 locus names
@loc.nall: number of alleles per locus
@loc.fac: locus factor for the  6 columns of @tab
@all.names: list of  6 components yielding allele names for each locus
@ploidy:  1
@type:  codom

Optionnal contents:
@pop:  factor giving the population of each individual
@pop.names:  factor giving the population of each individual

@other: - empty -

I am running 32 bit R version on a Windows 7 PC. I unintalled my R vers. 2.15.3 and installed R. vers. 3.0.2.
I have adegenet vers. 1.3-9.2. According to your web page, this is the most recent stable version, although adegenet-basics.pdf indicates that the adegenet version should be 1.4.
I have loaded the adegenet, pegas, MASS, and ade4 libraries.
I have searched the FAQ and every other source I can think of.

Help for an adegenet newbie will be most appreciated. NSF proposal deadline is looming ......
