Description Usage Arguments Details Value
Eye of storm score each segment in signature according to composition of local signature but without segment itself and some closest segments around it.
1 2 | eye_of_storm(signature, oligos = NULL, window = 100, eye = 5,
alpha = c(0.05, 0.025, 0.01))
|
signature |
signature from |
oligos |
either numeric or character vector of oligonucleotides that will be used. If nos specified, whole signature is used. |
window |
size of subset to the left |
eye |
number of segments around centered segment which are excluded from density estimation. |
alpha |
significance level of scoring intervals. |
Eye of storm is similar to sliding density, it uses subset of signature
centered around single segment, removes mentioned segment and some other
negihbouring segments specified by eye
parameter and then produce
density from this filtered subset of signature. Segment around which this
subset is centered is then scored based on credibility interval constructed
from estimated density.
Parameter window
does not specify whole size of subset taken, but only
left and right part. That means that it takes a window left from central
segment and window right. As first segment of signature doesn't have anything
on left and the last segment of signature doesn't have anything on right,
size of actuall subset range from (window+1) to (2*window + 1)
Parameter eye
define number of segments in signature (single number
that show frequency of oligonucleotide in part of sequence) that are excluded
from density estimation.
DIAS score for given signature.
