Sorry if this post should be long but I tried to give you a piece of my data
to reproduce my error message using hetcor:

Fehler in result$rho : $ operator is invalid for atomic vectors
Zusätzlich: Warning messages:
1: In polychor(x, y, ML = ML, std.err = std.err) :
  1 row with zero marginal removed
2: In polychor(x, y, ML = ML, std.err = std.err) :
  the table has fewer than 2 rows


Error in result$rho : $ operator is invalid for atomic vectors
Additional: Warning message:
1: In polychor(x, y, ML = ML, std.err = std.err) :
  1 row with zero marginal removed
2: In polychor(x, y, ML = ML, std.err = std.err) :
  the table has fewer than 2 rows

Use tab delimited data at the end of the post.
Copy in Texteditor and save as TestPart.txt 

Then use the following code

library(methods)
setClass("of")
setAs("character", "of", function(from) as.ordered(from)) 

Classe81<-cclasses <- c(rep("factor", 64),  rep("numeric",6), rep ("of",
12))

TestPart<-read.table("TestPart.txt", header=TRUE,row.names=1,
na.strings="NA" ,colClasses = Classe81)

str(TestPart)

library(polycor)

TestPart.hetcor<-hetcor(TestPart, use="complete.obs")

this will produce the above mentioned error message that I can not
interprete.

Would be great if somebody could help me to solve the problem.

Thanks

B.
