import2genind | R Documentation |
Their are several ways to import genotype data to a genind
object: i) from a data.frame with a given format (see
df2genind
), ii) from a file with a recognized extension, or
iii) from an alignement of sequences (see DNAbin2genind
).
import2genind(file, quiet = FALSE, ...)
file |
a character string giving the path to the file to convert, with the appropriate extension. |
quiet |
logical stating whether a conversion message must be printed (TRUE,default) or not (FALSE). |
... |
other arguments passed to the appropriate 'read' function
(currently passed to |
The function import2genind
detects the extension of the file given in
argument and seeks for an appropriate import function to create a
genind
object.
Current recognized formats are :
- GENETIX files
(.gtx)
- Genepop files (.gen)
- Fstat files (.dat)
- STRUCTURE
files (.str or .stru)
Beware: same data in different formats are not expected to produce exactly
the same genind
objects.
For instance, conversions made by GENETIX
to Fstat may change the the sorting of the genotypes; GENETIX stores
individual names whereas Fstat does not; Genepop chooses a sample's name
from the name of its last genotype; etc.
