[R] Error when naming rows of dataset

[yongchuan]

I get the following error when I try reading in a table.
How are 1.1, 1.2, 1.3 duplicate row names? Thx.

> table <- read.table('latestWithNumber.txt', header=T)
Error in "row.names<-.data.frame"(`*tmp*`, value = c("1.1", "1.2", "1.3",  : 
        duplicate 'row.names' are not allowed
