tutorial


This dataset is composed of a genotypic matrix called tutorial.R with 50 
individuals for 400 SNPs. The last 50 SNPs are correlated with an 
environmental variable called tutorial.C. This dataset is a subset of the 
dataset displayed in the note associated with the package.


LEA is an R package dedicated to landscape genomics and
ecological association tests. LEA can run analyses of
population structure and genome scans for local adaptation. It
includes statistical methods for estimating ancestry
coefficients from large genotypic matrices and evaluating the
number of ancestral populations (snmf, pca); and identifying
genetic polymorphisms that exhibit high correlation with some
environmental gradient or with the variables used as proxies
for ecological pressures (lfmm), and controlling the false
discovery rate. LEA is mainly based on optimized C programs
that can scale with the dimension of very large data sets.
