I have a chart with a set of 3 BoxPlots that all appear, depending on the code I made, in "gray" and I can not change that color. I leave here the code I have in the script. I asked for help to resolve this issue. Thank you.
C = list (performance_NN $ performance.rel, performance_VM performance $ Performance.rel, performance_ performance_RF $ Performance.rel) names (C) = c ("NN", "SVM", "RF") boxplot (C, col = rgb (0.5,0.5,0.5,0.5))
