I also suggest to apply a kernel density function to estimate the
probability of frequency of a certain value.

Import data by spgrass6 library

And then rely on sm package by:

require(sm)

set.seed(100)

sm.density(x, display="se", rugplot = F)

# display allows you to show the standard error...

Best!
