[R] duplicate 'row.names' are not allowed

[S Ellison]

Apologies; my earlier reply preceded this extra info.

If you are reading a large file with duplicate "row names", try reading
it in as is, then simply converting the numeric parts to a matrix.
For example, if you had the same kind of data frame as before

x1 <- rnorm(11,5,1)
x2 <- runif(11,0,1)
nam <- nam<-paste("A", c(1:4,4,5:9,9), sep=".")
mydata <- data.frame(nam=nam, x1=x1,x2=x2)

as.matrix(mydata[,2:3])

works.

You can also do this on the fly, as in 

biplot(prcomp(as.matrix(mydata[,2:3])))

to take a very silly example.

Yes, I would like, but what I sent you was just an example! I am
reading a huge data, so I cant do it by hand, could you please tell how
to do this in R, some of the names are also coming one after another.
 
Many thanks
