[R] indexing problem

[arnaud Gaboury]

Dear group,

Here is my environment :

> ls()
 [1] "l"          "PLglobal"   "Pos100415"  "Pos100416"  "Pos100419"
"Pos100420"  "position"   "select"     "Trad100415" "Trad100416"
"Trad100419" "Trad100420" "trade"      "y"  

With objects :

> l
 [1] "100415" "100416" "100419" "100420" "100421" "100422" "100423" "100426"
"100427" "100428" "100429" "100430" "100503" "100504" "100505" "100506"
"100507" "100510" "100511" "100512" "100513"

> select    #is a selection of elements of object "l"
[1] "100415" "100416" "100419" "100420"

"PLglobal", "position", "trade" are all functions
Pos100415,Pos100416,Trad100415...are all data frames

I have one dataframe each day. For example, Pos100415 is "Pos" for day
15/04/2010.

Now I need to access data.frames in my environment for a function, according
to this following scheme:

Pos100415 and Pos100416 (i.e. Pos(day1) and Pos(day2)), and Trad100416 (i.e.
trad(day2)).

I have absolutely no idea how to deal with this indexing problem in a
generic manner. Note that all numbers will belong to the list "select".

  
Not sur to be clear enough, but any help would be appreciated.

TY
