Yes! Thank you. Bottom line: for what I want to do the syntax is
facet_grid(row=vars(.data[[rowName]]),col=vars(.data[[colName]]))
Thanks again.
cheers,
Rolf

I need to call ggplot() from another function with the names of the
faceting variables supplied as arguments to the calling function.
These names (which are names of columns in the relevant data frame)
are given as character arguments, say "rowName" and "colName".
Suppose that rowName is equal to "clyde" and colName is equal to
"irving".
I'd like to do something like
... + facet_grid(row=vars(rowName), col=vars(colName)) + ...
but this does not work. For instance, vars(rowName) gives
[[1]]
<quosure>
expr: ^rowName
env: global
I'd like to get the same thing as if I said vars(clyde) which gives
<list_of<quosure>>
[[1]]
<quosure>
expr: ^clyde
env: global
There *must* be some magic arcane incantation that I can apply to
rowName (and colName) to get what I want. Mustn't there?
I tried things like vars(as.name <http://as.name>(rowName)) ---
nope, no help at all.
Can anyone help me out?
