I would like a function to strip quotes off character strings. I should
work like this:
> A <- matrix(1:6, nrow = 2, ncol=3)
> AF <- as.data.frame(A)
> names(AF) <- c("First","Second","Third")
> AF
First Second Third
1 1 3 5
2 2 4 6
> names(AF)[2]
[1] "Second"
> attach(AF)
> unquote(names(AF)[2])
[1] 3 4
Of course what I actually get is
Error: couldn't find function "unquote"
The reason that I want to do this is that I have a frame with a rather
large number of variables and I would like to loop over the names and
print out various descriptive summaries of the variable's distribution.
OK, OK, I could just go
> AF[,2]
[1] 3 4
but once I thought of unquoting I have some sort of inner need to know
how to do it!
Cheers,
Murray
