Dear R-help, I am using the plot3D package to produce 3D spheres along with 95% CIs distinguishing each sphere with a predefined colour (see the reproducible example at the end).
I have been successful in producing a similar plot using a different data set (kindly see https://www.dropbox.com/s/snpgiqgqaiqgpiv/exp1combined.pdf?dl=0), but in this case I cannot arrange the colours as desired. Specifically, the colours obtaind do not correspond to those in the "cols" object below (kindly see https://www.dropbox.com/s/nhljsuare84g811/test_exp2.pdf?dl=0). Any help/tips would be greatly appreciated. Thank you very much in advance.
