Call a variable from a data.frame stored in a list

I have created a function to transform data. It returns me a list of two dataframe: 

df1$v1 df1$v2 // df2$v1 df2$v2

dflist <- c(df1, df2)

I need to subset variables inside of each dataframe separately in a shiny app as reactive value.

I tried to subset them with 

dflist[[1]]["v1"]

But it's not subset as the 1st variable of the 1st dataframe of the list but as a data.frame

class(dflist[[1]]["v1"])

returns me dataframe, and I want the class of my variable instead.

Any ideas?

We need to do [[

dflist[[1]][["v1"]]

or use a , 

dflist[[1]][,"v1"]

because 

dflist[[1]]["v1"]

is still a data.frame of single column
