Hello,

I have trouble converting a character string to a R object. 
Let me describe this by an example;

dim(a)

[1] 270  14

dim("a")

NULL

names(a)

 [1] "Var1"  "Var2"  "Var3"  "Var4"  "Var5"  "Var6"  "Var7"  
"Var8"  "Var9" 
[10] "Var10" "Var11" "Var12" "Var13" "Var14"

names("a")

NULL

I realise that the character string lacks both a dimension 
and any column names; my question is how to make R understand 
that I look for the object a when I write "a".

Like a type cast in C;      (R data.frame) "a"      for those 
familiar with C.

The underlying reason for this is that I am writing a script 
that imports several datasets. The file names of the datasets 
contain the '_' character which forces me to construct a 
valid dataset name for each file. Although I can do this by 
hand, I would like to know if there is any solution to my 
first approach.

Thanks in advance,
Sixten
