If I do:

'a' = c(1:10)        
a
[1]  1  2  3  4  5  6  7  8  9 10

here I assign a vector to a string (variable) but i need to a do something like:

a = 'c10'

and then

a = c(1:10)

but the last a must to be c10

How can i do it?

Not sure what you're looking for but your first assignment doesn't need the c() and doesn't need quotes around the a.

a <- 1:10

if you want the last entry to be the string 'c10', you can get there a few different ways.

a <- c(1:9,'c10')

or

a <- 1:10
a[10] <- 'c10'

Or if Ben Bolker is on the right track:

a <- 'c10'
assign(a,1:10)
