Deepayan,

Thank you for your response. I tried your suggestion to manually specify the y-axis label for the factor but I am stuck. My attempt is below. I once again appreciate any input as well as your time. lattice/R-project is great.

Thanks once again,

David Arenas

# Example dataframe

test.df <- data.frame(acft=factor(c("A","B","C","D")),
                      status=factor(c("fail","pass","fail","pass")), 
                      site=factor(c("E1","E1","E2","E2")),
                      CD=as.numeric(c(1,1,3,3)),
                      H=as.numeric(c(80,NA,60,NA)))

# Your previous suggestion
xyplot(ifelse(status=="pass", as.numeric(site), H) ~ CD| acft,

       data=test.df,
       scales="free",
       xlim=c(0,4))

# My attempt to manually adjust the y-axis label for the factor "site"
# site has E1 & E2 that are read as 1 and 2, so I am trying to adjust # the ylim for acft B and D to c(0,2) but I get an error xyplot(ifelse(status=="pass", as.numeric(site), H) ~ CD| acft,
       data=test.df,
       scales="free",
       prepanel=function(x,y) {
                ylim <- if(test.df$status=="pass") 2 else 90
                list(xlim=range(0:4),
                     ylim=range(0:ylim)) }  )

I can't think of a clean way to do this. You could of course do

xyplot(ifelse(status == "pass", as.numeric(site), H) ~ CD| acft,

       data=test.df, scales = "free",
       layout=c(1,1) )

but this wouldn't give very nice axis labels for the factor (unless you specify them manually, which could be done).
