Creating string vector from loop

I am trying to create a label to the combn command so that I know exactly which pairs where compared. Here's an example: Let a be my vector of interest,

a<-seq(1,10,1)
c<-combn(a,2)

So I want to create a vector label with the numbers that are paired:

label<-rep("abc",times=ncol(c)) #This is just a vector to initialized "label"
head(label)

for(i in ncol(c)){
label[i]<-c(paste("Exon",c[1,i],"with",c[2,i]))
}
head(label)

The problem is when I run the for loop it doesn't work. Alternatively, it only outputs the last comparison.

Remove the loop and use a vectorized approach:

label <- paste("Exon", c[1,] "with", c[2,])

BTW: c is a very bad variable name (see ?c).
