You need to change the superpose.line setting: xyplot(Choline ~ time, groups=BMI, data=data, type="l", scales=list(relation="free"), auto.key=list(title="BMI Group", border=FALSE, lines=TRUE, points=FALSE), xlab=c("Point in Time"), ylab=c("Concentration of Choline"), par.settings = list(superpose.line = list(lwd=3))) > ############################################################ > > library(lattice) > > data <- data.frame(cbind(1:2,c(1,1,2,2), c(0.5,0.9,1.0,1.8))) > names(data) <- c("BMI","time","Choline") > > data$BMI <- factor(data$BMI) > levels(data$BMI) <- c("<=17.5",">17.5") > data$time <- factor(data$time) > levels(data$time) <- c("Admission","Discharge") > > > #Show names of settings > names(trellis.par.get()) > > #Try to set the line width of the two plotted colored lines > line<-trellis.par.get("plot.line") > line > line$lwd=3 > trellis.par.set("plot.line", line) > line > > > #Without group option: Line width is changed > xyplot(Choline ~ time, > data=data, > type="l", > scales=list(relation="free"), > auto.key=list(title="BMI Group", border=FALSE), > xlab=c("Point in Time"), > ylab=c("Concentration of Choline")) > > #With group option: Line width is not changed > xyplot(Choline ~ time, > group=BMI, > data=data, > type="l", > scales=list(relation="free"), > auto.key=list(title="BMI Group", border=FALSE), > xlab=c("Point in Time"), > ylab=c("Concentration of Choline")) > > ______________________________________________ > 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. > -- Chuck Cleland, Ph.D. NDRI, Inc.
