[R] introduce axis break lattice plot multipanel

[Duncan Mackay]

Hi Luigi

 

If you went down the relation = “free” road you could change the panel widths to reflect the scales 

eg if lhs was 1:200 and rhs was 1:100 then the lhs panel would be twice as wide as the rhs.

 

I have some code reasonably handy I could send it to you if needed.

 

Regards

 

Duncan

thank you duncan,
but in that case the scale of the two panel would be different. i think ill keep it as it comes.
best wishes of a merry xmas

Hi Luigi

I suppose a cheats way out would be to put

    scales = list(alternating = FALSE,
                  x = list(relation = "free") ),

Subject: [R] introduce axis break lattice plot multipanel

Dear all,
I am plotting some data using lattice's barchart. One of the counts I
am plotting has a very large value with respect to the other variables
and I would like to introduce a break in the axis to compensate for
this 'anomaly' and give more breath to the other bars. In this example
the high count is for the variable 'b' and I would like to introduce a
break of 50-100 in the x axis.
I have seen from the internet that the common approach is to stack
together two figures but in my case I am using a multipanel plot and I
think this way won't work for my plot.
Is there a simple way to introduce a break in the axis of a multipanel
lattice plot?
Thank you
L

the example:
>>>
A <- c('a',    'b',    'c',    'd',    'a',    'b',    'c',    'd',
'b',    'c',    'd',    'b',    'c',    'd')
B <- c(1,    1,    1,    1,    1,    1,    1,    1,    1,    1,    1,
  1,    1,    1)
C <- c(0,    0,    0,    0,    1,    1,    1,    1,    0,    0,    0,
  1,    1,    1)
D <- c(4,    120,    7,    23,    4,    24,    3,    12,    7,    1,
 1,    5,    0,    0)
E <- c(0,    0,    0,    0,    0,    0,    0,    0,    1,    1,    1,
  1,    1,    1)
DF <- data.frame(A, B, C, D, E, stringsAsFactors = FALSE)
library(lattice)
barchart(
    A ~ D|E,
    DF,
    groups = C,
    stack = TRUE,
    main = "Comparison of test results",
    xlab = "Count",
    col = c("yellow", "orange"),
    par.settings = list(
        strip.background = list(col="light grey"),
        superpose.polygon=list(col= c("yellow", "orange"))
    ),
    scales = list(
        alternating = FALSE
    ),
    key = list(
        space="top",
        columns=2,
        text=list(c("Single infections", "Multiple infections"),
col="black"),
        rectangles=list(col=c("yellow", "orange"))
    ),
)
