[R] concatenate values in the vector

[Cristian Montes]

Ok, sorry, I misinterpreted the question!  Here is the right solution

x <- c("a", "b", "c", "d", "e")
z <- x[1]

for (i in 2:length(x))
    {
     z<- paste(z, x[i], sep = "+")
    }

print(z)

[1] "a+b+c+d+e"

Cheers,

Cristián.

[1] "a" "b" "c" "d"

Except for the fact that it does not deliver what the OP appeared to  
be asking for. The paste function is vectorized, so if you give it a  
vector of length 4, it returns a vector of length 4. What was  
requested, at least up to the ambiguity left by no quotes around the  
requested ouput, was a single string.
