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. Uwe Ligges
In addition: Warning message:
non-unique values when setting 'row.names': ???A.4???, ???A.9???

I am very thankful for your help!
