Re: [R] Simple loop question

Here're a couple alternatives if you want to use the index instead of the variable name: # Reproducible data frame a1 - 1:15 a2 - letters[1:15] a3 - LETTERS[1:15] a4 - 15:1 a5 - letters[15:1] df - data.frame(a1, a2, a3, a4, a5) df # a1 a2 a3 a4 a5 # 1 1 a A 15 o # 2 2 b B 14 n # 3

Thank you very much! I used indeed rgl. The problem was apperently that I used text3d() in the wrong way. When I use it this way: plot3d(x, y, z,xlab=PC1, ylab=PC2, zlab=PC3, size=5) text3d(x=x,y=y,z=z,texts=names, col=4) It workes the way I wanted. So thanks again and have a nice

Re: [R] Contradicting results on stationary test!!!

This is a question about statistics theory, not about R, so it is off topic here... you might try discussing this at the CrossValidated forum. In general, the amount of lag that is relevant depends on how you intend to use the data. This is not unlike the application of linear models to

Re: [R] Consistent size dashes...

If you rename two or more levels with the same string, R collapses them. Using gsub like you suggest works well. If there are more than the two characters causing problems you may need to expand the pattern that's being matched. With the example you sent, this works: df - structure(c(6L, 4L,
