Here i have a variable
MyVar <- data.frame(read.csv("D:\\Doc.csv"))
And now i am storing this variable name into a list.
MyList <- list()
MyList [length(MyList )+1]<- "MyVar"
Now what is the requirement is,
i need to call the variable name "MyVar" from the list "MyList
" and get
the data.
------------------------------------------------------------------------------------------------------------------------
i tried with get(MyList [1]). - it not work-out.
Can you please help me ?
- Thanks in advance
Antony.

Hello, And this: get(MyList[[1]]) with [[ ]] instead of [ ] ? If you do for example: MyList <- list() MyList [length(MyList )+1]<- "MyVar" MyVar <- c(1:10) get(MyList[[1]]) It seems to do what you want -- View this message in context: http://r.789695.n4.nabble.com/Get-variable-data-Reading-from-the-list-tp4641559p4641563.html Sent from the R help mailing list archive at Nabble.com.

As before, you really don't want to be using get() and assign() for this sort of stuff though. Please do try to do things the idiomatic way: it'll be easier in the long run : I promise.
