Dear Alessandro I am not sure what you mean by "conditional plot"
But if it is about having a different symbol, for different soil parent materials, you can use the pch argument in TT.plot() ####### require( soiltexture ) # :: 1st create a dummy texture dataset my.text <- data.frame( "CLAY" = c(05,60,15,05,25,05,25,45,65,75,13,47), "SILT" = c(05,08,15,25,55,85,65,45,15,15,17,43), "SAND" = c(90,32,70,70,20,10,10,10,20,10,70,10), "parent"= rep(1:2,each=6) # parent material and symbol code ) # dim( my.text ) TT.plot( tri.data = my.text, pch = my.text[,"parent"] ) ####### Is that what you need?

I have data from the particle size distribution of soils derived from two parent materials and I want to use the parent material as conditioner. Thanks a lot.
