[R] mixing different modes of lty line type specification in legend() ?
Hi List,
is sth. like the following possible:
legend(x,y,c("A","B","C"),
lty=list(1,"42","11")) ?
Or: is there a possibility to define a solid line using the "string"
mode for lty?
Thanks
Marcus

Hi, ----- Original Message ----- From: "Marcus Eger" <eger.m at gmx.de> To: "r-help" <r-help at stat.math.ethz.ch> Sent: Wednesday, June 05, 2002 10:06 PM Subject: [R] mixing different modes of lty line type specification in legend() ?> Hi List, > is sth. like the following possible: > > legend(x,y,c("A","B","C"), lty=list(1,"42","11")) ?I am assuming you want to fit the three lines with line type 1, 42, and 11? If this is so you need something like: legend(x,y,c("A","B","C"), lty=c(1,42,11)) Or you can use: legend(x,y,c("A","B","C"), lty=c("solid", "dotted", "dashed")) which draws solid line for A, dotted line for B and dashed line for C. I hope this is what you want :-) Cheers, Ko-Kang Wang --------------------------------------------- Ko-Kang Kevin Wang Post Graduate PGDipSci Student Department of Statistics University of Auckland New Zealand www.stat.auckand.ac.nz/~kwan022 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

As an alternative, one could use: legend(x, y, c("A","B","C"), lty=c("11", "22", "42"),lwd=3) But, unfortunately, solid lines do not seem to supported in "string" mode.

I think it is because legend simply does not process lty elements less equal zero (not distinguishing between strings and numbers): "legend" <- function( ....... ...... if (do.lines) { seg.len <- 2 ok.l <- if (missing(lty)) { lty <- 1 TRUE } else lty > 0 browser() .......

The problem with the patterns is that they recycle and thus give alternating on/off values by definition. Curiously, "0" gives a solid line in plot() but not in legend(), whereas "00" works in both places. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
