Re: [R] s-plus to R

[Tony Plate]

I'd suggest just removing the "+" and see if that works.  It's somewhat 
difficult to say whether that would be safe without seeing more of your 
code, but "+" as a unary operator on character vectors seems to be an 
identity function in S-plus 6.1, e.g.:

> print(+ letters[1:3])
[1] "a" "b" "c"
> deparse(+ letters[1:3])
[1] "c(\"a\", \"b\", \"c\")"

Maybe it has some side effects in S-plus (like invisible()?), but if the 
code depends on these you will probably have to code these in a different 
way in R anyway.  I don't know -- I haven't before seen "+" used as a unary 
operator on character vectors.

hope this helps,

Hi, I have a piece of code originally written for s-plus - I am trying to
run it in R now. The code was obtained from someone who is now not
available to give any pointers and I am a beginner in R. Here is where it
is getting stuck:
> +names(good.motifs[,1])
Error in +names(good.motifs[, 1]) : Invalid argument to unary operator
here is now names(good.motifs,1]) looks:
> names(good.motifs[,1])
[1] "Motif.P1.8.3"  "Motif.P1.9.14" "Motif.P1.10.1" "Motif.P1.11.8"
[5] "Motif.P1.15.1"
Can anyone help with an equivalent in R?

Thanks,
