plot discrete data set

We really need some usable sample data.

is not it. Firstly

x= [0.14504024 , 0.18261047, -0.09171451 ,-0.09171451, -0.09171451 ,-0.09171451 ,-0.09171451 ,-0.09171451, -0.09171451 ,-0.09171451, 0.14160323 , 0.14160323, 0.14160323 -0.09171451 ]

is not a valid statement in R

x  = c(0.14504024 , 0.18261047, -0.09171451 ,-0.09171451, -0.09171451 ,-0.09171451 ,-0.09171451 ,-0.09171451, -0.09171451 ,
    -0.09171451, 0.14160323 , 0.14160323, 0.14160323 -0.09171451)

or preferably

x  <-   c(0.14504024 , 0.18261047, -0.09171451 ,-0.09171451, -0.09171451 ,-0.09171451 ,-0.09171451 ,-0.09171451, -0.09171451 ,
    -0.09171451, 0.14160323 , 0.14160323, 0.14160323 -0.09171451)

are valid.

is meaningless in relation to x since x has 13 elements and there is no obvious way to expand y to 13 elements.
