I´m building a lattice graph with the following code
table.df<-means
library(lattice)
library(gridExtra)
graph1<-barchart(value1~Var1|Var2+Var3,data=table.df, ylab=NULL)
graph2<-barchart(value2~Var1|Var2+Var3,data=table.df, ylab=NULL)
grid.arrange(graph1,graph2, nrow=2, ncol=2)
I´m trying to merge the comum strips. For example the first strip from the first graph would be merge into a unique strip (normalVar3).
Any suggestion?
