Your first solution solved it perfectly!
Thanks,

Hi Paolo,
I am assuming the raster is being warped/projected upon rendering. By
default we use 'bilinear' resampling.
2 possible solutions:
1) set the method for projecting with mapview(rst, method = "ngb") for
nearest-neighbor resampling
2) set mapview(rst, native.crs = TRUE) so that the raster does not get
projected and hence not resampled (though you'll lose the background
maps).

I'm trying to plot a raster where pixels can only assume integer values
1, 2 or 3, identifying 3 land use classes. The map does fine when
plotted with the base r function: plot(rastername). However, I would
like to use mapview (or another package for interactive maps) but it
creates pixels with non-integer values on transition boundaries between
classes (eg between classes 1 and 2 it creates a transition zone with
some pixels assuming non-integer values 1.2033, 1.4221, 1.7119, etc.).
Any way to avoid this? Thanks in advance, PauloFR
