[R] Convert a character string to variable names

[Erin Hodgess]

Hello!

I have a character string that is a vector of variable names.  I would like
to use those names to access the variables and create a matrix.
I tried the following:

> .x

[1] "mtcars$disp" "mtcars$hp"   "mtcars$cyl"

> .y <- NULL

> for(i in 1:3) {

+ .y[i] <- c(as.name(.x[[i]]))

+ }

> .y

[[1]]

`mtcars$disp`


[[2]]

`mtcars$hp`


[[3]]

`mtcars$cyl`


But I am having trouble converting the variables in .y into a matrix.


I tried all kinds of stuff with bquote, deparse, do.call, but no good.


I have a feeling that it's something simple, and I'm just not seeing it.


Thanks,

Erin
