phyDat {phangorn} | R Documentation |
These functions transform several DNA formats into the phyDat
format.
allSitePattern
generates an alignment of all possible site patterns.
phyDat(data, type = "DNA", levels = NULL, return.index=FALSE, ...) ## S3 method for class 'DNAbin': as.phyDat(x, ...) ## S3 method for class 'phyDat': as.character(x, ...) ## S3 method for class 'phyDat': as.data.frame(x, ...) allSitePattern(n, levels=c("a","c","g","t"), names=NULL)
data |
An object containing sequences. |
x |
An object containing sequences. |
type |
Type of sequences ("DNA", "AA" or "USER"). |
levels |
Level atttributes. |
return.index |
If TRUE returns a index of the site patterns. |
n |
Number of sequences. |
names |
Names of sequences. |
... |
further arguments passed to or from other methods. |
If type
"USER" a vector has to be give to levels
.
For example c("a", "c", "g", "t", "-") would create a data object that
can be used in phylogenetic analysis with gaps as fifth state.
allSitePattern
returns all possible site patternsis and can
be usefull in simulation studies.
The functions return an object of class phyDat
.
You may import data with read.dna
or read.nexus.data
.
