when i run : knnDecision(x.tr, y.tr, x.te, y.te, k = 15) . Error in viridisLite::viridis(256, alpha, begin, end, direction, option) : unused argument (option)

I am sorry ,but the problem persists . my Info: R version 3.3.2 (2016-10-31) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 7 x64 (build 7601) Service Pack 1 and viridis_0.4.0

Actually,after I reinstall the viridisLite package,the knnDecision() works.Thanks a lot for your help!
