as.SNPbin | R Documentation |
The class SNPbin is a formal (S4) class for storing a genotype
of binary SNPs in a compact way, using a bit-level coding scheme. New
instances of this class are best created using new
; see the
manpage of SNPbin for more information on this point.
As a shortcut, conversion methods can be used to convert various
objects into a SNPbin object. Conversions can be
achieved using S3-style (as.SNPbin(x)
) or S4-style
(as(x,"SNPbin"
) procedures. All of them call upon the
constructor (new
) of SNPbin objects.
Conversion is currently available from the following objects: - integer vectors - numeric vectors
