I'm writing code which subsets from a dataframe a lot e.g. lots of dataframe_name$column_name and it's a pain to read and to write. Is there a way to tell R that I'm referencing dataframe_name so that I can just write column_name for each instance?

I am assigning a large odd number to a variable (1126605209290117121) and it is being shown as (1126605209290117120) [observe the last digit] in the environment. But assigning a large even number is represented correctly. Can someone explain why?
a = 1126605209290117121
print(as.character(a))
[1] "1126605209290117120"
After searching through the internet I learned that R still has only 32-bit integers.

Is there a way to add superscript to a character string in R? For example can the '2' here be superscript:
"cm2"
Using unicode, you can check it with the [link][1]
cat("\U0063\U006D\U00B2")
cm²
