[R] RE : creating character vector

[Wolfgang RAFFELSBERGER]

Jim,

I don't know if this is the most elegant solution :

Copy the following to your clipboard (some editors will require also to take last paragraph mark)
first
second
third

> ## now go to R and use
> dat <- read.table("clipboard")  # will give data.frame
> dat
      V1
1  first
2 second
3  third
> ## or if you want a character-vector
> dat <- as.character(as.matrix(read.table("clipboard")))
> dat
[1] "first"  "second" "third"

Objet : [R] creating character vector

Is there a way to convince R to create a character vector without using the quotes?

This works

ex1 <-  c("first","second")

but when I try this it doesn't

ext <- as.character(c(first,second))

it complains. I have many variables to put into character vectors so dispensing with the quotes would be useful.

Thanks

Jim
