[R] R Markdown and scan()

[John Fox]

Dear JJ and list members,

I wonder whether it's possible to get scan() to read in-line data in an R Markdown document. The following code, for example, works (of course) when entered in the R console but fails in an R block in an R Markdown document (using an up-to-date version of RStudio):

```{r}
x <- scan()
1 2 3
4 5 6

x
````

I'm aware of a couple of work-arounds, such as putting the data in a file or a character string (as below), but am interested in whether it's possible to get this to work directly.

```{r}
text <- "
1 2 3
4 5 6
"
(x <- scan(file=textConnection(text)))
````

Any help would be appreciated.

John
