[R] Change order of columns in table?

[Gabor Grothendieck]

Assuming you really do have a table,

> tab <- as.table(c(Friday=119, Monday=173, Saturday=80,
+ Sunday=96, Thursday=167, Tuesday=193, Wednesday=194))
> tab
   Friday    Monday  Saturday    Sunday  Thursday   Tuesday Wednesday
      119       173        80        96       167       193       194

we can  use the fact that May 17, 2010 is a Monday to write this:

> tab[format(as.Date("2010-05-17") + 0:6, "%A")]
   Monday   Tuesday Wednesday  Thursday    Friday  Saturday    Sunday
      173       193       194       167       119        80        96

This last line should also work if tab is a data frame rather than a table.
