R help - Feb 2013 - Error in R (ENFA) : Error in eigen(Se) : infinite or missing values in 'x'

Dear all,

I am running an Ecological Niche Factor Analysis in R but I am stuck with a
problem. As soon as I ask the software to compute the ENFA, I get the
following error message:

Error in eigen(Se) : infinite or missing values in 'x'

Does anyone know what could be wrong. I do not have missing values in my
dataset.

Please follow the codes I used for my analysis so far:

library (adehabitat)

 library (ade4)


(dataenfa1 <- data2enfa(var, locs))

pc <- dudi.pca(dataenfa1$tab, scannf = FALSE)

(enfa1 <- enfa(pc, dataenfa1$pr, scannf = FALSE))

Error in eigen(Se) : infinite or missing values in 'x'


Any help will be much appreciated.

Thank you,

Leandro
