error in `row.names<-.data.frame`(`*tmp*`, value = value) : duplicate 'row.names' are not allowed

Answer 1

You can probably use make.names(..., unique = TRUE) to get your unique row names

rownames(diasyhoras2) <- make.names(diasyhoras[,1], unique = TRUE)

Following is the quick example of what will happen to the names ...

rep(month.abb[1:2], 3)
# [1] "Jan" "Feb" "Jan" "Feb" "Jan" "Feb"
make.names(rep(month.abb[1:2], 3), unique = TRUE)
# [1] "Jan"   "Feb"   "Jan.1" "Feb.1" "Jan.2" "Feb.2"

If you follow above approch your issue will be resolved.
