| as methods in adegenet {adegenet} | R Documentation |
These S3 and S4 methods are used to coerce genind and
genpop objects to matrix-like objects. In most cases,
this is equivalent to calling the @tab slot. An exception to
this is the convertion to ktab objects used in the
ade4 package as inputs for K-tables methods (e.g. Multiple Coinertia
Analysis).
as(object, Class)
objectClass"data.frame" or "matrix".as(object,"Class"), where the object is of the old
class and the returned object is of the new class "Class".Thibaut Jombart t.jombart@imperial.ac.uk
data(microbov)
x <- na.replace(microbov,method="0")
as(x[1:3],"data.frame")
## dudi functions attempt to convert their first argument
## to a data.frame; so they can be used on genind/genpop objects.
if(require(ade4)){
## perform a PCA
pca1 <- dudi.pca(x, scale=FALSE, scannf=FALSE)
pca1
x <- genind2genpop(microbov,miss="chi2")
x <- as(x,"ktab")
class(x)
## perform a STATIS analysis
statis1 <- statis(x, scannf=FALSE)
statis1
plot(statis1)
