calling an object with a numeric name

I loaded some data in R and mistakenly named it as 86. Now when I want to call the data frame I end up with the number 86 instead of my data set. Is there a way to call the data set rather than the number 86? Also, is there a way to change the name of the data so it is no longer a number? Thank you.

You need to use backticks:

"86" <- data.frame(a = "meow", b = "wouf")
> `86`
#      a    b
# 1 meow wouf

To change the name of your data frame, simply assign (<-) data from 86 to df and remove (rm) the original 86

df <- `86`; rm(`86`) 
> df
#      a    b
# 1 meow wouf

Because of copy-on-modify, this will not allocate memory for df. 

> "86" <- data.frame(a = "meow", b = "wouf"); tracemem(`86`)
# [1] "<0x3936b28>"
> df <- `86`; tracemem(df)
# [1] "<0x3936b28>"
