Hello, this code below was from a helpful R-help user. dat <- read.csv("Resid_fix2.csv", sep="," , header=T) dat11 <- dat[1:413,] # convert ambiguous columns to factors: dat11$Pri_No <- factor(dat11$Pri_No) dat11$RecovUnit <- factor(dat11$RecovUnit) # plot: require(lattice) bwplot(bbED~ Pri_No | RecovUnit, data=dat11, as.table=TRUE, layout=c(4,1))
This works, but I am trying to do this: > bwplot(bbED~ Pri_No | RecovUnit, data=dat11, subset = (Pri_No %in% c(1,2)), as.table=TRUE, layout=c(2,1)) Error in limits.and.aspect(prepanel.default.bwplot, prepanel = prepanel, : need at least one panel How can I choose only two groups from 'Pri_No'?
