Have you tried the density function:

> a <- read.table('/users/jim/downloads/LG_freq.txt',header = TRUE)
> str(a)
'data.frame':   669 obs. of  2 variables:
 $ Position : Factor w/ 669 levels "chr1_103381212",..: 308 463 458 160 393
457 165 464 3 467 ...
 $ frequency: num  75 62.5 50 48.9 47.1 ...
> plot(density(a$frequency))

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
