My R code like this:

as.character(c(x[1],recursive = TRUE))

as.numeric(c(x[2],recursive = TRUE))

I really don't know what's the meaning of the recursive parameter. Sometimes, I eliminate this parameter and lead to some error message, but sometimes are normal. I can't find any help information in R, so I hope someone can help me.

    Try to be more specific, i.e. please post a [**minimal, reproducible example**](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example/5963610#5963610) with a relevant set of `x`, together with the error message. Also read [about getting help in R](http://cran.r-project.org/doc/manuals/R-intro.html#Getting-help). – Henrik Nov 26 '13 at 14:02

It is a parameter of the c function:

recursive logical. If recursive = TRUE, the function recursively descends through lists (and pairlists) combining all their elements into a vector.

It is essentially the same as calling unlist on x[1]. It would only have an effect if the elements of x are list like objects.
