[R] Weighting data with normal distribution

I have a vector of binary data – a string of 0’s and 1’s.
I want to weight these inputs with a normal kernel centered around entry x
so it is transformed into a new vector of data that takes into account the
values of the entries around it (weighting them more heavily if they are
near).
Example:
-
- -
- -
0 1 0 0 1 0 0 1 1 1 1
If x = 3, it’s current value is 0 but it’s new value with the Gaussian
weighting around would be something like .1*0+.5*1+1*0+0.5*0+.1*1= 0.6
I want to be able to play with adjusting the variance to different values as
well.
I’ve found wkde in the mixtools library and think it may be useful but I
have not figured out how to use it yet.
Any tips would be appreciated.
Thanks!
