Dear R users,
This probably a really noob question, but I'm stuck. I'd like to
pass some
variables from bash to R as strings. I can successfully pass
variables using
commandArgs(), the problem is that I end up with an array.
Huh? You should be getting a character vector.
So, for example:
Args <- commandArgs(TRUE)
Args
[1] "one" "two" "three"
Now, it just so happens that "one", "two", "three" are names of
columns
.... columns? Of what? Or perhaps ... in what? Does this "what" have a
name in the R workspace?
that
I'd like to work with. I'd like to do something like this:
print(summary(lm(Args[1] ~ Args[2])))
No 'data' argument to lm. You would be getting better answers if you
provided more specifics.
But, this doesn't work. The alternative would be to let bash write a
number
of R-scripts and then rm them when done, but that seems like an
unnecessary
step.
Can this be done?
require(fortunes)
fortune("Yoda")
Thanks
