Dear R users
I use bwplot to plot some figures. There are two troubles:
1. How to change the dot of the mean to a line, like the style in
boxplot
Sometimes you need to refer the the help page for panel.<type of
plot>, in this case:
?panel.bwplot
... so the answer is now staring you in the face:
bwplot(decrease ~ treatment, OrchardSprays, groups = rowpos, pch="|")
2. How to hide some tick marks. For example, I have seven tick: A,
B, C, D,
E, F, G,
but I want show four marks: A, C, E, G on the x-axis.
Using the example in bwplot again, and a fair amount of fruitless
experimentation with the theory that one could do anything useful with
scales=list(at= list(<something>)), I finally ended up trying ,
labels=c( ) per Sarkar's Lattice book, producing this:
bwplot(decrease ~ treatment, OrchardSprays, groups = rowpos,
scales=list(x=list( labels=c("A","","","D","","F","","") )))
