grunwaldlab/poppr: Poppr Version 2.6.0

The biggest feature of this release is the scaling of nodes by area in the minimum spanning networks. More details on that here: https://zkamvar.github.io/blog/poppr-2-6-0-better-network-plotting/ NEW FUNCTIONS The new function boot.ia() is conceptually similar to resample.ia(), except it resamples with replacement. NEW FEATURES The function resample.ia() now can resample individuals weighted by their Psex value. The minimum spanning networks will now scale nodes by area instead of radius. This gives a more accurate picture of the differences between MLGs. See https://github.com/grunwaldlab/poppr/issues/154 for details. A legend for samples/node is now added to all minimum spanning networks. See https://github.com/grunwaldlab/poppr/issues/158 for details. The imsn() option for node size scale has been changed to a slider. BUG FIX An issue where data with sample names containing apostrophes could not be imported was fixed (Identified in https://github.com/grunwaldlab/poppr/issues/156). a bug in imsn() where custom MLGs would result in an error was fixed. See https://github.com/grunwaldlab/poppr/issues/155 for details. a bug in plot_poppr_msn() where setting scale.leg = FALSE would result in a very small MSN plot was fixed. mlg() now works properly for snpclone and genlight objects. See https://github.com/grunwaldlab/poppr/issues/155 for details. DEPENDENCIES The minimum version of igraph has been set to 1.0.0
