dataframe name as a variable in R

I know how to do this in Python, but right now I need to use R. I have a large dataframe with 15m records and 65 variables. I have subset the data to smaller regions of interest and I want to use the subset name as a variable in later steps in my script. For example 

x <- subset(largedata, Name=="Test").

How to I get the name x as a variable, not as a data input?

Alternative approach, split your data on Name column, then you have a named list, try this example:

mySplitData <- split(iris, iris$Species)

mySplitData
# $setosa
#    Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1           5.1         3.5          1.4         0.2  setosa
# ...
# $versicolor
#     Sepal.Length Sepal.Width Petal.Length Petal.Width    Species
# 51           7.0         3.2          4.7         1.4 versicolor
# ...
# etc

# to access by name:
mySplitData$setosa
#    Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1           5.1         3.5          1.4         0.2  setosa
# ...

In your example it would be something like:

mySplitData <- split(largedata, largedata$Name)
