• How to cite mixOmics?

It depends… See here to cite the paper corresponding to your need.

• How to extract the names of variables selected when performing sPLS?

We will update a new version to extract theses genes in a most explicit manner. For now it is, for example for component 1 to extract the genes selected from data set X:

comp = 1
which(result$loadings$X[, comp] != 0)

You can do the same for component 2 and 3 and also for the data set Y.
Beware that the absolute value of these loadings indicate the importance of these genes so you can actually sort your list:

loadingsX1 = abs(result$loadings$X[, comp])
