Jorge,

Your line works and give the desired result. Now I need to be able to work
with i instead of 100419..., as I need to be able to change these numbers. 
TY for your help

Hi Arnaud,

Try the following (untested):

txt <- paste('DailyPL',c("100419", "100420", "100421"), sep = "")
do.call(rbind, lapply(txt, get))

HTH,
Jorge

Dear group,

Here is my environment:

> ls()
 [1] "DailyPL100419" "DailyPL100420" "DailyPL100421" "dd"            "i"
"l"             "PLglobal"      "Pos100416"     "Pos100419"     "Pos100420"
"Pos100421"     "position"
[13] "result"        "sel"           "Trad100416"    "Trad100419"
"Trad100420"    "Trad100421"    "trade"

With "sel" the following element :

sel <-
c("100419", "100420", "100421")


"DailyPL100419" , "DailyPL100420","DailyPL100421" are all data frames with
same columns names. I want to rbind them with this condition :


for (i in sel[-1])

I have no idea how to write it.

TY for any help
