Dear R-users,
i have two questions :

1- first of all, i wish to know the way to obtain a serie with a format like "00" : ( "01","02","03","04"....) or like postal code ("01100","02222").
for instance, i do :
> format(strptime(as.character(c(1:4)),"%H"),"%H")
but it sounds complicate and not really efficient....!

 2- i search to generate a serie of hours and minutes on 24h : "00:00" , "00:01", "00:02", "00:03", ...,..., "23:59" for instance, i do :
> x <- format( strptime (as.character(rep(0:23,each=60)),"%H"),"%H")
> y <- format( strptime (as.character(rep(0:59,24)),"%M"),"%M")
> paste (x,y,sep=":")

it works but is it an another way to obtain this ?

thanks
Bruno
