Hello all,
I am going to be running a small statistics workshop using R sometime
in November. I am restricted to R because of the specific libraries I
will be using - a good thing in my book - however the attendees are
unfamiliar with R. I plan on giving as little R information as
possible - ju

First, data is an R function so it is better to avoid it as a name for

colnames(dat)
[1] "Sepal.Length" "Sepal.Width" "Petal.Le

Also, your test data and code snippet you give are not quite consistent.
Thus, my advice is really a long-shot guess.
Assume your data looks like:

Hi...
Is this possible in R?
I have 2-sets of data, that were collected simultaneously using
2-different data acquisition schemes.
The x-values are the same for both.
The y-values have different ranges (16.4-37.5 using one method, 557-634

How about:
