Do you mean you want to separate out each sequence of characters that does not contain whitespace? scan can do that:
> Line <- "if C325=. then C743=(C152/C103)*100| else C743=(C152/C325)*100" > scan(textConnection(Line), what = "") Read 6 items [1] "if" "C325=." "then" [4] "C743=(C152/C103)*100|" "else" "C743=(C152/C325)*100" On 5/14/07, elyakhlifi mustapha <[EMAIL PROTECTED]> wrote: > hello, > I need help because for my training I need to write a lil program which is > able to read a line of character and it would recognize words > for example for this line of character > > if C325=. then C743=(C152/C103)*100| else C743=(C152/C325)*100 > > the program will be able to recognize the IF ELSE syntaxe and the equations > thanks > > > > _____________________________________________________________________________ > > [[alternative HTML version deleted]] > > ______________________________________________ > [email protected] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
