Re: [R] customizing the color and point shape for each line drawn using lattice's xyplot
I have succeeded in controlling the line colors and point symbols of each
Method plotted in each frame of my xyplot, using the help files you
suggested so that some methods can be represented by the same color and
distinguished by symbols using the following code (I can not, however, seem
to make the key reflect these color and symbol changes):
#assign colors to each method
lcol <- rep(0, 243)
lcol[common$Method==1] <- 1
lcol[common$Method==2] <- 2
lcol[common$Method==3] <- 3
lcol[common$Method==4] <- 6
lcol[common$Method==5] <- 4
lcol[common$Method==6] <- 4
lcol[common$Method==7] <- 5
lcol[common$Method==8] <- 5
lcol[common$Method==9] <- 6
#assign the type of symbol that corresponds to each method
ptype <- rep(0, 243)
ptype[common$Method==1] <- NA
ptype[common$Method==2] <- NA
ptype[common$Method==3] <- NA
ptype[common$Method==4] <- 3
ptype[common$Method==5] <- 6
ptype[common$Method==6] <- 2
ptype[common$Method==7] <- NA
ptype[common$Method==8] <- NA
ptype[common$Method==9] <- NA
xyplot(Yvar~ Xvar| Avar * Bvar, data=common.without.Method478,
groups=method.not478.f, type="o", col=lcol, pch=ptype, cex=0.5,
auto.key=list
(text=c("Method 1","Method 2","Method 3","Method 4a","Method 4b","Method
9"), points = TRUE, lines = TRUE, col=c(1,2,3,4,4,6), cex=1,
pch=c(NA,NA,NA,6,2,NA)))
The above code obtains the desired plot, and is the closest that I have come
to obtaining the desired key. Using the above code, within the key, I
obtain the appropriate text and the text is colored such that the text
"Method 1" corresponds to the color of method 1 in the plot. The symbol
shape and line color to the right of this text, however, does not change
from its default settings, and therefore does not reflect the plot. I am
trying to obtain black text with appropriate symbols and appropriately
colored lines to the right.
Have I misinterpreted the syntax of the atuo.key function?

Some general comments: 1. try type = "o" for both points and lines, and auto.key = list(points = TRUE, lines = TRUE) if you meant this for the legend. 2. The number of distinct colors is 7 by default, after which they get recycled. You can set the colors by changing the superpose.line$col setting (see ?trellis.par.set and the entry for 'par.settings' in ?xyplot) 3. The number of colors used is related to the number of levels of 'groups'. If you want fewer colors (or not have unused colors in the legend), you need to make sure your 'groups' variable has a suitably reduced set of levels. There is no cute way to do this. The long way is subdata <- subset(common, Method != 4) subdata$Method.f <- subdata$Method.f[, drop = TRUE] -Deepayan __ R-help@stat.math.ethz.ch 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.

Re: [R] customizing the color and point shape for each line drawn using lattice's xyplot
Thank you for your suggestion. Unfortunately it does not appear to matter if the data is subsetted before the xyplot command or within it. The problem remains. I was able to remove method 4 entirely from the key by using your suggestion to subset the dataset “common,” and then creating a new variable to assign labels for just this subset “common.without.Method4$method.not4.f” The resulting code was: xyplot(MeanBxg ~ PercentVarExplained | bdg.f * bdx.f, data=common.without.Method4, groups=method.not4.f, type="l", auto.key=T) This however leads to lack of continuity between plots, as when I exclude methods 4 and 6 in my second plot, using the same approach, the color that had corresponds to methods 7, 8 and 9 in plot one is automatically changed in plot two. The subsetting may work, so long as I can dictate line color and symbol type in each plot.
