[R] Help with concatenation and arrays

[VBMorozov@lbl.gov]

Dear R-guRus:
I have 2 questions

1) I have 2 variables, e.g. x<-5; y<-"Char"
How do I create a new variable which would have both these values in a 
string (e.g. "5Char", or "5 Char", etc ) ??

2) if i have an array x[1:100], and I do x[x==345.123], how do I get 
position j in the array of those x[j] which are equal to 345.123 ?

Thank you very much,
Vlad.
