Hi, I was wondering if there's a function in R that is meant to return a string representation of an object. Basically, it's like print() but it doesn't print anything, it only returns a string. I know there's a str() function but it's not quite the same. I mean a function that returns the same string that print() would display.
Bye, Ernest

Jim Holtman Data Munger Guru What is the problem that you are trying to solve? Tell me what you want to do, not how you want to do it.
Possibly as.character() is what the OP was seeking Michael

Use capture.output(print(yourData)) to capture would be printed by print as a vector of a strings (one per line of printout). Paste together if desired. Use deparse(yourData) to get a string representation that can be parsed by R (useful for sending to others who are using R). Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com

Thanks for the suggestions, but none of these appears to do what I need. Take a table such as
a <- as.table(c(A=450,B=12)) a
A B 450 12 The string that print() prints is " A B \n450 12 \n". Once you have the string you can print it with cat() and get the same result as with print().
cat(" A B \n450 12 \n")
A B 450 12 The function that I was looking for was one that given the table a in the example would return the string described above. Apparently, capture.output() can be used for that, although it returns the string split into lines they can be joined together easily. So, case closed :)
Bye, Ernest

This will do it!! Thanks.
