R-Help community, I understand that data.frames can hold elements of type double, string etc but NOT objects (such as a matrix etc). This is not convenient for me in the following situation. I have a function that takes 2 inputs and returns a vector:
testfun <- function (x,y) seq(x,y,1) I have a data.frame defined as follows: testframe<-data.frame(xvalues=c(2,3),yvalues=c(4,5)) I would like to apply testfun to every row of testframe and then create a new column in the data.frame which holds the returned vectors as objects. Why do I want this? Because the returned vectors are an intermediate step towards further calculations. It would be great to keep adding new columns to the data.frame with the intermediate objects. But this is not possible since data.frames can not hold objects as elements. What do you suggest as an elegant solution in this scenario? Thank you for any help! I would love to hear if forum ______________________________________________ R-help@r-project.org 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.
