Hi all,

I'm running the LCA procedure within the E1071 package.  I'm receiving 
the following message that I don't understand

 > lcaread <- read.csv("~/Documents/Teaching/EP 773/EP 773 Examples/LCA 
Example/lca.reading.csv", header=TRUE)
 > attach(lcaread)
 > readclass <- lca(lcaread, 3)
Error in pas[j, ] <- drop(exp(rep(1, nvar) %*% log(mp))) :
  number of items to replace is not a multiple of replacement length
 > print(readclass)
Error in print(readclass) : object "readclass" not found
 > summary(readclass)
Error in summary(readclass) : object "readclass" not found

Thanks in advance,
