feature request: Repel labels in plotIndiv and plotVar

[aljabadi]

Would be good if the plots could take a repel=<logical> arg with style='ggplot2'. Use code below as guide to what should work.

See https://mixomics-users.discourse.group/t/repel-labels-in-plotindiv-and-plotvar/621

data(nutrimouse)
X <- nutrimouse$lipid
Y <- nutrimouse$gene
nutri.res <- rcc(X, Y, ncomp = 3, lambda1 = 0.064, lambda2 = 0.008)
plotIndiv(nutri.res, cex=5,  ind.names = TRUE, repel=TRUE, group = nutrimouse$diet) 
plotVar(nutri.res, comp = c(1,3), cutoff = 0.5, repel = TRUE)

Hi @aljabadi,
I use mixOmics version 6.18.1 and the repel argument works in plotIndiv() but not works in plotVar() retrieving me the following error:

Error in plotVar(nutri.res, comp = c(1, 3), cutoff = 0.5, repel = TRUE) : 
  unused argument (repel = TRUE)

I have installed BiocManager::install('aljabadi/mixOmics@ggrepel') although the following error appeared:

Error in fetch(key) : 
  lazy-load database '/media/vant/TextesD/R_packages/mixOmics/help/mixOmics.rdb' is corrupt

Or I need to update my R current version (4.1.2) to a newer one to install mixOmics 6.20 version that I understand that the argument repel appear included in the plotVar() function.

Thanks on advance for your help,

Maggie.
