Arguments

x

Position at which the density should be evaluated.

minDist

Minimum distance between nucleosomes.

varDist

Variance of nucleosome distances.

meanDist

Mean distance of nucleosomes.

minLength

Minimum fragment length.

maxLength

Maximum fragment length.

meanLength

Mean fragment length.

bind

Position of binding site within fragment.

length

Length of region.

weight

Weight of feature.

stable

Density function for stable nucleosome.

dist

Density function of distances between nucleosomes.

shift

Distance between alternative position for stable nucleosome.

ratio

Ratio of probability mass associated with central and alternative positions for stable nucleosome.

stability

Stability of stable nucleosome.

fragLength

Length of DNA fragment. If x is not in [0, 1] this is used to normalize x.

Value

Density evaluated at the given position.
