Hi,

For eg:-  
MyVariable <- "UnitNo"

Here my requirement is, i need to get "UnitNo" as another variable by
reading "MyVariable"

i need  "UnitNo" as variable name and need to assign some value into

Hello,

Try the following, supposing that 1:5 is the value you want to assign.

?assign
MyVariable <- "UnitNo"
assign(MyVariable, 1:5)
UnitNo

Hope this helps,

Ok.
Here I have a variable called "Variable_1".

Variable_1 <- "MyDataFrame"

Here I want to create another variable, by assigning the value of
"Variable_1" .
So, it will come like,

Assign(Variable_1,data.frame(read.csv("c:\\Mydata.csv")))  
--->[this
was the 1st requirement, now I got the solution]

Now, " MyDataFrame " is a variable and containing some values in that.
And Now, the problem what is I need to do "rbind" into the variable
"
MyDataFrame ".

I tried to do,
rbind(as.character(Variable_1),
data.frame(read.csv("c:\\My2ndData.csv")))

Here I am getting stuck !


- Thanks
Antony

Others have mentioned assign and get, but generally when the answer to
a question is "assign" it means that you are asking the wrong question
(see fortune(236)).

This is actually FAQ 7.21, the most useful part of the answer in the
FAQ is the last few lines.

If you tell us more about what you are actually trying to accomplish
then we have a better chance of giving you useful advice that is less
likely to lead to future frustration.
