[R] lattice question: removing strips

[Duncan Mackay]

Hi Martin

If you only had 1 strip then strip = FALSE would suffice.
With 2 I think you are getting into the realm of strip.default because of the first 2 arguments 

strip.default(which.given,  which.panel, ....)

and having to modify it 

An easy solution is 

library(latticeExtra)

useOuterStrips(strip = FALSE,
  xyplot(y ~ x | f1 + f2, data=data, strip = FALSE)
 )

and to change the strip background to blank or whatever colour
useOuterStrips(strip = FALSE,
  xyplot(y ~ x | f1 + f2, data=data, strip = FALSE,
               par.settings = list(strip.background = list(col = "transparent"))
 )
 )
you can format strip.left in the useOuterStrips function.  See
?latticeExtra::useOuterStrips 
for details

And now to bed

Dear Pascal, 
Thank You very much for Your reply. Here is a minimal working example:

library(lattice);
# this is with both strips plotted:
data <- data.frame(x=1:5, y=6:10, f1=c("a1", "a1", "a1", "a2", "a3"), f2=c("b1", "b2", "b2", "b1", "b2"));
p <- xyplot(y ~ x | f1 + f2, data=data)
print(p);

# and this is my attempt to only plot the strips for the second conditioning variable, i.e. for f2:
my.strip <- function(which.given, strip.levels, ...) {
  if(which.given == 1) {
    return(FALSE);
  }
  else {
    strip.default(which.given=which.given, strip.levels=c(TRUE, FALSE), ...);
  }
}

p1 <- xyplot(y ~ x | f1 + f2, data=data, strip=my.strip)
print(p1);

#As You can see, here I do not get the strips for f1 potted, but there is an empty space below
the strips for f1, which I cannot get rid of. I only want to show the strips for f2. Directly
below them I want to see the panels themselves, instead of an empty space for the missing f1 strips.

Any suggestions?

Best regards,

Martin
