Hello;
I followed V&R's example and tried to set trellis parameters using
trellis.par.set():
>sps <- trellis.par.get("superpose.symbol")
>sps$pch <- 1:7
>trellis.par.set("superpose.symbol", sps)
The function resulted an error msg:
>Error in trellis.par.set: Missing value where logical needed: if(p[i] !=
q[i]) stop("inconsistent component names")
Tracing back to the trellis.par.set(name, value)
>dev <- get(".Device", where = 0)
>current <- attr(dev, "trellis.settings")[[name]]
I found the attr() returned NULL given dev = "graphsheet" and name =
"superpose.symbol".
Did I miss anything? I am using Splus 4.5 Professional on NT sp3.
Any help is appreciated.
Richard
