read.fstat {adegenet} | R Documentation |
The function read.fstat
reads Fstat data files (.dat) and
convert them into a genind object.
read.fstat(file,missing=NA,quiet=FALSE)
file |
a character string giving the path to the file to convert, with the appropriate extension. |
missing |
can be NA, 0 or "mean". See details section. |
quiet |
logical stating whether a conversion message must be printed (TRUE,default) or not (FALSE). |
There are 3 treatments for missing values:
- NA: kept as NA.
- 0: allelic frequencies are set to 0 on all alleles of the concerned
locus. Recommended for a PCA on compositionnal data.
- "mean": missing values are replaced by the mean frequency of the
corresponding allele, computed on the whole set of
individuals. Recommended for a centred PCA.
