Hi everyone,
 
I have got the following problem:
 
x1 <- rnorm(10,5,1)
x2 <- runif(10,0,1)
nam1 <- paste("A",1:4,sep=".")
nam2 <- paste("A",6:9,sep=".")
nam <- c(nam1,"A.4",nam2,"A.9")
mydata <- data.frame(x1,x2)
rownames(mydata) <- nam
Error in `row.names<-.data.frame`(`*tmp*`, value = c("A.1", "A.2", "A.3", : 
duplicate 'row.names' are not allowed

This message suggests that you have to choose unique row.names ... or 
assign those values as an additional column in your data.frame, if you 
need non unique values.

In addition: Warning message:
non-unique values when setting 'row.names': ‘A.4’, ‘A.9’
 
I am very thankful for your help!
 
Amor
