well thank you, i think we get closer to my problem. but i meant it in a different way. maybe i describe what i intended to do:
i have number of triangles which i'd like to store in a list, matrix,...etc. i thought it could look sth. like that: triangle node1 node2 node3 ..... 1 c(x1,y1) c(x2,y3) c(x3,y3) 1 c(x4,y4) c(x5,y5) c(x6,y6) . . . i know that i could just make more rows for the x/y values but the problem is, that i need to store more than these properties (say the neighbours of these nodes and their coordinates) and i thought it would be more convenient to save these as vectors. it was just a thought... is this possible? -- View this message in context: http://r.789695.n4.nabble.com/vector-entry-in-matix-tp4635478p4635509.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
