Hi I have 10 variables and 2 groups. I know how to plot a bwplot for ONE var. e.g. var.a var.b var.c .. GROUP 0.2 0.5 0.2 .. 0 0.3 0.2 0.2 .. 0 .. 0.1 0.8 0.7 .. 1 0.5 0.5 0.1 .. 1 .. bwplot(var.a ~ GROUP, data = my.data) How can I plot 10 bwplots (or boxplots) automatically into one graphic? is there any function from lattice which can do this? thanks for a short hint christoph
Your variables (var.*) seem to be on the same scale. How about
reshaping the data into a univariate layout and then using bwplot as
follows:
mydata <- data.frame(ID = 1:20, A = runif(20), B = runif(20),
C = runif(20), GROUP = rep(c(0,1), c(10,10)))
mydata.uni <- reshape(mydata, varying = list(c("A", "B",
"C")),
v.names = "Y", timevar = "VAR", times
= c("A",
"B", "C"), direction =
"long")
library(lattice)
bwplot(Y ~ as.factor(GROUP) | VAR, data = mydata.uni, layout=c(3,1,1),
xlab="Group")
hope this helps,

You can reformat your table to long format to get second grouping (a,b,...) by reshape (or reShape from Hmisc) and than use interaction and boxplot or bwplot(Group~var|second.grouping) Cheers Petr> > thanks for a short hint > > christoph > > ______________________________________________ > R-help at 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.htmlPetr Pikal petr.pikal at precheza.cz
