hi all,
I load a table with headers that enable me to acces it by the column names:
tab<-read.table("blob/data.dat",h=T)
attach(tab)
everythings are OK, but i try to sort this table against one of his column like
this:
tab<-tab[order(tab$IndexUI),];
It is still ok, the table is sorted, if i type "tab" i see a sorted table.
but, when i call the column by their names, it appears that the column isn't
sorted...
I believe that, is there a solution to attach column names another time, to
reflect the effect of sorting this table?
thks all for your answers
guillaume.
