[R] problems with 'eval' and 'parse' with strings

2008-04-02 Thread salcaraz
Hi R-friends: I don't understand very well the parser. if I do: p=v= q=5 eval(parse(text=paste(p,q,sep=))) ... then the value of v is 5, OK. but I can't with strings, for example: p=v= q=hello friend eval(parse(text=paste(p,q,sep=))) .. error and, I would need that v has the value
