Combine two vectors in R, convert to string

I have two numerical vectors in R

c(1,2,3,4,5)
c(0.1,0.2,0.3,0.4,0.5)

I would like to convert them to strings, combine them, and apply formatting, producing one vector:

c("1 (10.0%)", "2 (20.0%)", "3 (30.0%)", "4 (40.0%)", "5 (50.0%)")

It's more important for the solution to be simple and comprehensible than performant in my case.

Here's a very simple implementation: 

> num      <- c(1,2,3,4,5)
> pct      <- c(0.1,0.2,0.3,0.4,0.5)
> 
> pctChar  <- paste0("(", pct*100, "%", ")")
> char.out <- paste(num, pctChar)
> char.out
[1] "1 (10%)" "2 (20%)" "3 (30%)" "4 (40%)" "5 (50%)"

Note that paste0() by default does not put spaces between the components, and that paste() does.

x<-c(1,2,3,4,5)
y<-c(0.1,0.2,0.3,0.3,0.4,0.5)

y <- paste0(y * 100, "%")
result <- paste0(x," (", y, ")")
