converting a string to an integer vector
Hi All,
Thanks in advance for your help. I'm trying to convert a string to an
integer vector. For instance, I will start with
a <- "1,2"
The result I want to end up with will be the equivalent of
c(1,2)
What's the best way to make the conversion? I've tried using as.integer(a),
but R seems to balk at that.
Thanks,
Ben

...e help file) the image looks
the same as with 1:3, the only difference being that the scale runs from 0
to 1 (with splits at 0.25 and 0.75).
Can I influence this behaviour and how?
Thank you for your help! Regards,

How to document man/*.Rd pages with images?
Hi,
I?m trying to figure out how to put images into my package?s help
documentation. I?ve gotten to the point where I can put the images in the
/inst/doc/ directory. I have also gotten to the point where I have package
checks without any warnings. I couldn?t find the terms ?picture,? ?image,?
or ?graphic? in a text search within the Writing R Extensions: 2 Writing R
documentation files

[1] FALSE
Any suggestions how to achieve this? Many thanks!

avoiding (another) error
...xy
$a
[1] 1 2 0
$b
[1] 2 3
So obvisouly R does what I would like it to do. How can I get it to do it
without the error? The problem is that I need to do this within a
function.
Thanks for ideas and hints! Regards,
