Hi everyone. I'm trying to customize a biplot (RDA). I would like to remove all axes ticks. Therefore, I was using *ann=FALSE* (see following example). However, it only clear the axis 1 and 2 leaving ticks on axis 3 and 4. Any suggestions to get rdi of the remaining ticks? data(varespec) data(varechem) ## Common but bad way: use all variables you happen to have in your ## environmental data matrix vare.cca <- cca(varespec ~ Al + P*(K + Baresoil), data=varechem) vare.cca plot(vare.cca, xaxt = 'n', yaxt = 'n', ann=FALSE) With regards, Phil -- View this message in context: http://r.789695.n4.nabble.com/Remove-axes-in-boplot-tp4639779.html Sent from the R help mailing list archive at Nabble.com.
