I am making an rgl-based 3d plot. It works fine, except when I try to remove axis value labels and tick marks with axes3d(labels=FALSE, ticks=FALSE): --------------------------- rgl.open() offset <- 50 par3d(windowRect=c(offset, offset, 1280+offset, 1280+offset)) rm(offset) rgl.clear() rgl.viewpoint(theta=thetaStart, phi=30, fov=30, zoom=1) spheres3d(df$PC1, df$PC2, df$PC3, radius=featureRadius, color=df$rColor, alpha=featureTransparency, shininess=featureShininess) aspect3d(1, 1, 1) /* ------ */ axes3d(col='black', box=FALSE, labels=FALSE, ticks=FALSE) /* ------ */ title3d("", "", "PCoA1", "PCoA2", "PCoA3", col='black', line=1) texts3d(df$PC1, df$PC2, df$PC3, text=df$ctName, color="blue", adj=c(0,0)) bg3d("white") rgl.clear(type='lights') rgl.light(-45, 20, ambient='black', diffuse='#dddddd', specular='white') rgl.light(60, 30, ambient='#dddddd', diffuse='#dddddd', specular='black') filename <- paste("results/PCoA.labeled.pdf", sep="") rgl.postscript(filename, fmt="pdf") --------------------------- When I run this code, these flags are ignored and I still get axis labels and tick marks. What am I misunderstanding about the documentation? Thanks, Alex [[alternative HTML version deleted]]
