[R] write a table to file with unequal length of lists

[Rolf Turner]

What about

	> x <- 1:2
	> a <- list(c(4,5),c(8,9,10)) # Which is the way you *should*
                                      # have constructed a!
	> ddd <- data.frame(x=x,a=I(unlist(lapply(a,paste,collapse=","))))
	> write.table(ddd,file="ddd.out",quote=FALSE,row.names=FALSE)
