[R] quiry on paste() function

[Ivan Calandra]

Hi,

It would be interesting to have such behavior, but I think you would 
then need to specify every separator, for example like this:
paste("a", "b", "c", sep=c(",", ",", ":"))
Otherwise, R cannot know where to put each separator.

So at the end, it's not much different from several paste() calls, isn't it?

It could be possible to write your own function, but I have not much 
idea how (I mean to make it work in every case, independently of the 
number of separators)

> Hi all, I want to club different objects (character type) to a single one and using paste() function that can be done happily. However the problem with paste function is the separator field is unique for all underlying objects. If I put separator as "-" then this will come in between all underlying objects which are to be clubbed.
