more fun, log transform these variables before plotting so that parts
of the variable names are also part of the valid code. For me, coding is hard
enough without additional complexity.

I suggest you study a bit more about types of join (a.k.a. merge) operations.
In particular, most of the time you will want to use inner join or left join
operations with large data sets. In order to avoid problems with duplication
you will need to pay close attention to which set of columns can
> Variable names cannot have spaces
Please soften your words... variables can have all sorts of characters
including spaces in them, but it can be inconvenient to quote them all with
back-tick quotes like `merged 1` so where possible most people avoid variable
names with weird characters.

Some issues:
1) Variable names cannot have spaces. "merged 1" is not valid but "merged_1" is
a valid alternative.
2) You need to tell R what to merge by. It looks like you may be using data
tables rather than a data frame.
merged <- dataset2[dataset1, on = "id", nomatch = NA]
3) Alternatively: j
